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.

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.
