Scientists are worried about the future of some species that have experienced extreme decreases in both population size and gene
tic diversity, including cheetahs, bison, and elephant seals. Using the concept of genetic diversity, explain why these animals may be in trouble even if their population sizes have increased in recent years.
If an animal changes the way it acts to stay alive, this is called a behavioral adaptation. For example, some geese fly south in the fall. This behavior allows them to stay warm and find food during winter. Changes in an animal’s body are called physical adaptations. A chameleon can change color to hide from its enemies
