Compare the way that frogs breathe when they are tadpoles with the way frogs breathe when they are adults.

Answer explanation

Frogs breathe differently when they are tadpoles than when they are adults. When frogs are tadpoles, they use gills to breathe. Gills help the tadpole get oxygen from water. When frogs are adults, they use lungs to breathe.

What are some structural adaptations of adult frogs that help them survive in their environment? Explain how each adaptation helps the frogs.

Answer explanation

Long, strong back legs help frogs jump far. Their color helps them blend into the environment to help avoid predators. Webbed feet help them swim. Long tongues allow them to catch insects.
