Sahara Desert: The Sahara Desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions.
Bromeliads: Bromeliads grow on tree trunks and branches and wrap their roots around the trees. They need wet habitats to grow well. They have a center portion like a cup or bowl that collects water. Their leaves are waxy, and the water slides into the center. The leaves are long and curved to collect water.
How well would a bromeliad survive in the desert?
When reviewing the facts about a desert and the bromeliad plant, the bromeliad does not have the traits or attributes needed to survive. Bromeliads need trees, a wet environment, and lots of rain. The desert is the opposite type of habitat and not ideal for a bromeliad to live.

Panda: This bear is huge and can weigh up to 300 pounds. It has very thick black and white fur that keeps it warm when it is cold or chilly outside. It primarily eats bamboo but will also eat rodents, grass, and meat if needed. They drink their water from streams and rivers. They take shelter in hollow trees and the holes between rocks.
Sahara Desert: The Sahara Desert is made entirely of sand. It rarely rains and is very dry. There are only a few plants, and they have small leaves. The sand is scorching and moves every time it is touched; when the wind blows, the sand shifts in all directions.
Based on the information provided, how well would the panda survive in this habitat, and why?
In this habitat, the panda would not survive. The panda has thick fur to protect it against cold weather, and the desert is sweltering, so it would overheat quickly. It's black and white coat would offer no camouflage in the sand, and there is no water source for the panda to drink from. The food sources that pandas rely on are not available in the Sahara. The panda would not survive in this habitat because it is not adapted to live there.

Some organisms cannot survive in a habitat that has had members removed.
The statement is true. If the primary food source has been removed from an environment, some of the organisms will not survive. An example is if ants were to be removed from the forest, there would be an adverse chain reaction. Anything that eats ants would need to adapt or face starvation. If they could not adapt and died, this would start the next wave of changes to the habitat because another food source is gone. Some organisms will not survive a slight shift in the ecosystem.

Which animal would NOT survive living in or around a freshwater lake and why?
A dolphin would not survive living in or around a freshwater lake. A dolphin is an aquatic creature meaning it lives in water, but it lives in saltwater. Dolphins are found in the ocean, not ponds or lakes. A dolphin does not have the right traits to survive living in freshwater.

Grasslands - The grasslands in the Northern hemisphere are vast, open terrains with flowers and grass. There is enough rain to support small amounts of trees and lots of grass. The soil is thin and dry, and there are often wildfires. The temperatures range from very cold (in the negatives) to comfortable (in the mid-70's).
Which animal would NOT survive in this habitat, and why?
A polar bear would not survive in this habitat because none of its basic survival needs would be met, and it does not have the inherited traits for the environment. Polar bears live on sea ice in freezing habitats and primarily eat seals. They have thick fur and a layer of fat to keep them warm. They are solitary creatures who hunt through openings in the ice. There would be no ice, seals, or constant freezing temperatures in a grassland habitat to support the bear.

Amazon Rainforest: In the Amazon Rainforest is rains almost every day. There are very tall trees that create a canopy, and the ground of the forest is covered in plants. The plants on the ground try to grow wide or tall to reach sunlight. The very tall trees can block much of the sunlight.
Which animal would most likely NOT survive in this habitat, and why?
In this type of environment, it would be tough for a hawk to survive. Hawks hunt small mammals that they spot with their keen eyesight on the ground in grassy fields and open areas. They fly high above, looking for prey and swoop down on them. In a rainforest, it can be dark, and there is limited open space to hunt. It would be difficult for hawks to adapt and find food.

Which organism would NOT survive in this habitat, and why?
In this habitat, the deer would not survive. Deer need woodlands or tall grass to blend in and camouflage from predators. They have hooves that are not suited to the shifting, scorching sands. The deer would not survive in this habitat because it is not adapted to live there.
Compare your answer with the correct one above
Which animal would NOT survive living in a saltwater ocean, and why?
An alligator would not survive living in the saltwater ocean. An alligator is an aquatic creature meaning it lives in water, but it lives in freshwater. Alligators are found in ponds, swamps, or lakes. An alligator does not have the right traits to survive living in saltwater.

Jackson wants to get a pet lizard for his bedroom. He has a tank with sand, a small water bowl, a heat lamp, and low humidity. He goes to the pet store with his brother to pick one out. The lizards come from many different habitats and have special needs that must be met. Which habitat should Jackson NOT get a lizard from for the type of tank he has?
Jackson's tank is not humid, cold, or wet, so any lizards from those types of habitats would not survive. Jackson needs to find a lizard that requires the kind of tank he has. It must be able to live in low humidity, high temperatures, and on the sand with limited water.
Compare your answer with the correct one above
A sunflower plant can survive in all types of environments and habitats.
The statement in the question is false. Sunflowers are adapted to live in specific areas based on their roots, pollination requirements, water intake, water storage, and sunlight requirements. If moved to an area that does not have the conditions necessary to meet the plant's needs, it will not survive.

Natalie, Mike, and Melissa are arguing about why some organisms don’t survive as well as others in a habitat. They are thinking about a habitat like a rainforest as an example.
Which answer choice contains the best argument of why some animals wouldn’t survive as well as others in a rainforest?
The best argument for why some organisms don't survive as well as others in a habitat is Natalie's. The reasoning she gave was clear and correct. If animals don't have the right traits for that particular environment, they will not survive as well. If something changes in their habitat and they don't adapt quickly, they may not survive as well as another plant or animal.
Compare your answer with the correct one above
Organisms and their habitats depend on each other for survival. What would happen if one member of the habitat was removed?
Within each habitat, there is a balance that allows its members to thrive and survive. If one member is removed, it throws off that balance and affects the food chain and other organism's survival chances. Other organisms may not survive as well if one member is removed. If bamboo is removed from a forest where panda lives, then the panda is at risk for starvation because bamboo is their primary food source. One simple change can cause a ripple effect with other organisms.

Barrel Cactus - The barrel cactus is large and shaped like a barrel with spines and small flowers. The plant can reach up to seven feet tall. It likes to be in the full sun and only needs to be watered occasionally.
Grasslands - The grasslands in the Northern hemisphere are vast, open terrains with flowers and grass. There is enough rain to support small amounts of trees and lots of grass. The soil is thin and dry, and there are often wildfires. The temperatures range from very cold (in the negatives) to comfortable (in the mid-70's).
When comparing the grasslands environment to the desert where the cactus is usually found, how well will the organism survive, and why?
The grasslands are not the barrel cactus' natural habitat, so it does not have all of the features or characteristics that would make an ideal habitat. It does have plenty of sun, occasional rain, and open areas to grow, which would work well for a cactus. The cactus may not grow as well as it would in the desert and may need to adapt to the new environment to survive.

Alligators are freshwater reptiles that need warm, wet environments to live. They can live in areas with short periods of cold but cannot stand long, harsh winters. They can eat a wide variety of prey (fish, turtles, small/medium mammals, etc.) and can move from water source to water source. They are able to live for short periods in saltwater but need freshwater long term.
Which habitat would an alligator be able to live in, but less well than its natural environment?
An alligator would be able to survive in a tropical rainforest with large lakes and ponds better than any of the other choices. It may not survive as well in this habitat when you compare it to the swampy areas they thrive in, but it would have all of its basic needs met.

Many birds of prey like the osprey live in areas with lots of open bodies of water for hunting. They have terrific eyesight and can spot a fish from many feet in the air and dive down to scoop them out of the water with their sharp talons and strong feet.
Which habitat would an osprey be able to survive in, but less well when compared to its natural habitat?
The osprey would be able to survive in a swamp but maybe not as well as in its natural habitat. The wetland has other predators that hunt similar food sources and make nests where the ospreys would so it would have to compete for these basic needs to be fulfilled. Ospreys also have large open bodies of water for hunting, and many swamps have thick canopies from the trees. An osprey can survive in a swamp, but it would not do as well as native birds.

Organisms and their habitats depend on each other for survival. Some survive better than others, depending on the conditions.
Within each habitat, there is a balance that allows its members to thrive and survive. Organisms depend on one another for survival. If there were no prey for predators in a habitat, they would die out, be forced to relocate, or have to adapt to the new changes. Some organisms survive better in habitats than others, and it is dependent on their ability to adapt to their changing surroundings.

Alligators are freshwater reptiles that need warm, wet environments to live. They can live in areas with short periods of cold but cannot stand long, harsh winters. They can eat a wide variety of prey (fish, turtles, small/medium mammals, etc.) and can move from water source to water source. They can live for short periods in saltwater but need freshwater long term.
Based on the provided information, if an alligator is moved to a Northern state, what would most likely happen?
Northern states are known to have cold winter, and in many areas they experience long periods with freezing temperatures and frozen water. Alligators cannot survive in the winter months in a Northern state. The alligator may be fine during the warmer seasons but would not survive all year. Many alligators are moving further north in the United States, but they are still not able to reach the upper Northern states due to the cold winters.

Allison, Rachel, and Erik are arguing about why some organisms don’t survive as well as others in a habitat. They are thinking about a panda bear as an example.
Which answer choice contains the best argument of what would happen to a panda bear if moved to a desert?
The best argument for what would happen to panda bears if moved to the desert is Rachel's argument. The reasoning she gave was clear and correct. If animals don't have the right traits for that particular environment, they will not survive as well. If something changes in their habitat and they don't adapt quickly, they may not survive as well as another plant or animal.

What would happen to an organism if it was moved from its natural environment to somewhere new?
If an organism is moved from its natural habitat, it may not survive as well as it did previously. If the new environment has different conditions (weather, food source, water source, etc.), it may not be able to adapt. If an organism has specific natural adaptations to a desert environment, for example, it will have difficulty living somewhere cold or very wet because it is not suited to it.

Bromeliads: Bromeliads grow on tree trunks and branches and wrap their roots around the trees. They need wet habitats to grow well. They have a center portion like a cup or bowl that collects water. Their leaves are waxy, and the water slides into the center. The leaves are long and curved to collect water.
Which habitat would a bromeliad be able to survive in, but less well when compared to its natural habitat?
A bromeliad is a plant that thrives in warm wet environments. They are typically found in tropical and sub-tropical areas, so they may survive in a swamp. Swamps are damp and have a lot of trees and standing water, but depending on the location, rain is not as frequent as places bromeliads usually live. They may survive in the swamps but not as well as their natural habitats.
