Adaptations of Form and Function of Living Things to Their Environment: Practice Questions

Polar bears live in the icy Arctic where everything is covered in snow. They have thick white fur. Which of the following is the best reason for this structural adaptation?

Many animals show specific behavioral adaptations to survive seasonal changes. What is the main difference between hibernation and migration?

In high-latitude forests, Coniferous trees (such as pines and firs) must survive long, cold winters where liquid water is frozen and heavy snowfall is frequent. These trees possess needle-like leaves, a thick waxy cuticle, and a sloping, conical (cone-like) shape. Which of the following best evaluates how these structural adaptations work together to ensure the tree's survival during winter?

When the environment becomes very cold and food is hard to find in winter, some animals like bears or frogs enter a state of deep sleep. What is this behavior called?

Water lilies are plants that grow in ponds. They have very broad, flat leaves that float on the surface of the water. Why is this feature important for the plant's survival?

Sea otters live in cold ocean waters but do not have a thick layer of blubber like many other marine mammals. How does their extremely dense fur help them survive in this environment?

Contrast the survival strategies of migration and hibernation used by animals to survive harsh winter conditions in terms of energy conservation.

Many animals have colors or patterns on their skin or fur that match their natural surroundings. Identify this type of adaptation and explain how it helps both a predator and its prey to survive in the wild.

a) Describe two specific adaptations (physical or behavioral) that a camel possesses to survive in the hot, dry desert environment. Explain how each adaptation helps it survive. (4 points)

b) Describe two specific adaptations (physical or behavioral) that a polar bear possesses to survive in the cold, icy polar environment. Explain how each adaptation helps it survive. (4 points)
