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?
Which scenario below is an example of plants being affected by an environmental change?
Researchers were digging in the desert when they came across a fossilized cactus leaf buried in the sand.
Environments can change over time. Some places stay the same. What might this environment have been in the past?
All organisms follow a life cycle, even humans. In the model below, what is the missing piece of the cycle?
Newborn Infant
Child
___________
Adult
Elderly
Which example(s) is a learned behavior rather than an inherited trait?
Meerkats live in large families. Some are look-outs while others care for the young. Other meerkats are in charge of digging tunnels, and some are hunters. The meerkats will trade jobs and take turns.
What could happen to the meerkats if they started living alone instead of in groups?
Why does the puppy in the photo below look so similar to both of its parents?
Pollinators prefer plants that have strong smells and brightly colored flower petals when they are selecting a place to collect nectar like the one pictured below. How does this variation in appearance give them an advantage in reproducing?
A population of dark-colored moths moves into an area with light-colored moths. The area has lots of birch trees. The dark-moths stand out against the white and grey trees. More dark moths are eaten by predators than light moths. Only moths that live to reproduction age will produce offspring.
Which moth or moths has the advantage because of their traits to get the change of reproducing?
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?
