Detailed explanation-1: -Change in an organism’s environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species.

Detailed explanation-2: -For populations that can both disperse and evolve in response to a changing environment, gene flow among populations with different environments may limit local adaptation and restrict the geographic range of the population or even cause extinction [74], [75].

Detailed explanation-3: -Adaptations are inheritable characteristics that increase an organism’s ability to survive and reproduce in an environment. Adaptations can help an organism find food and water, protect itself, or manage in extreme environments.

Detailed explanation-4: -Animals may respond to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship. As a result of cold, winter weather (stimulus) some animals will hibernate. Hibernation is a state of greatly reduced body activity, used to conserve food stored in the body.
