b. Hummingbirds have long-thin beaks that they insert into flowers to get nectar.
c. These birds have large talons that they use to capture prey to eat.

4.
A young crocodile is basking in the warm sunlight.
How is this an example of a behavioral adaptation?

b. They have very long ears, and they have short but powerful tails for swimming.
c. These animals have very thick fur for cold weather, and like all mammals they are cold blooded.
____
6. One structural adaptation displayed by plants is the shape and size of their leaves. Different plant species have different
shaped leaves depending on their environment.
Which diagram below most likely shows an adaptation that increases the chances of survival of a plant in a hot,
dry climate?
a.
b.
Wild Yam Leaf
____
c.
Water Lily Leaf
Cactus Leaf
7. All organisms must adapt to their environment in order to survive and reproduce. If an organism can not adapt to a
change in its environment then it will die. If too many of the individuals die then the entire species will go extinct.
Which of the following events would most likely cause a rapid extinction of organisms?
a. A regional drought brought on by slowly moving tectonic plates
b. A large asteroid impact could cause extinctions due to fast changes in the environment
c. A gradual decrease in the growth of weeds in a meadow over a 1000 year time period.
____
8. All organisms including fish, mammals, reptiles, birds, insects, and bacteria adapt to their specific habitats by changing
their behavior or their body structure or both.
Which of the following behavioral adaptations is best suited for survival in an environment with harsh,
extremely cold, and long winters?
a. webbed feet
b. hibernation
c. defensive behavior
____
9. Alligators are carnivorous reptiles. One behavioral adaptation they display is ambushing animals that come down to the
water’s edge. Two structural adaptations they have is nostrils on top of their long snouts and eyes located high up on
their skulls. These two adaptations allow alligators to float in the water with most of their body hidden beneath the
surface.

b. a hot and dry desert
c. frozen tundra
a. a murky swamp
