SCI.3.4.1

What effect could the following change have on populations?

Change in the environment: There is a thunderstorm and part of a forest catches on fire.

• Some animals might die due to a loss of habitat, but the population will probably survive and will continue to live in the area.

• Over time, animal populations might stop migrating to warmer places.

• Over time, populations of plants might adapt different structures for their roots to survive in the wetter conditions.

• Over time, the consumers will start to eat different plants. Their teeth may adapt to the new food.

SCI.3.4.1

What effect could the following change have on populations?

Change in the environment: A drought causes a plant population to die out.

• Some animals might die due to a loss of habitat, but the population will probably survive and will continue to live in the area.

• Over time, animal populations might stop migrating to warmer places.

• Over time, populations of plants might adapt different structures for their roots to survive in the wetter conditions.

SCI.3.4.1

What effect could the following change have on populations?

Change in the environment: The climate changes. The temperature increases greatly so that the winter months are not as cold.

• Some animals might die due to a loss of habitat, but the population will probably survive and will continue to live in the area.

• Over time, animal populations might stop migrating to warmer places.

• Over time, populations of plants might adapt different structures for their roots to survive in the wetter conditions.

• Over time, the consumers will start to eat different plants. Their teeth may adapt to the new food.

SCI.3.4.2

Which of these is a behavioral adaptation? Select the best answer.

• A plant grows deep roots so that it can get water during times of drought.

• A fish is camouflaged so that predators cannot see it easily.

• A grizzly bear hibernates in the winter in order to save energy.

• A shark has a flexible body in order to move more quickly through the water.

SCI.3.4.2 

Which of these is a physical adaptation? Select the best answer.

• Butterflies migrate to warmer areas during the winter.

• A bird uses a special call to tell other birds where it is.

• Mosquitoes fly towards warm animals.

• Ducks have oil on their feathers to help them stay dry.

SCI.3.4.3

A scientist searching for fossils in a pit found one in the middle of a grassland ecosystem that looked like this.

What can the scientist conclude? Select the best answer.

•  The grassland ecosystem was once an aquatic ecosystem.

• An organism like this probably still lives in the area.

• The organism had adaptations to help it survive in the grassland ecosystem.

• The only other fossils in the area would be organisms that have adaptations for terrestrial ecosystems.
