Detailed explanation-1: -It is essential for students to know that a complex set of responses to stimuli is called behavior. Behavioral responses refer to how animals cope with changes in their environments. Animals may respond to environmental stimuli through behaviors that include hibernation, migration, defense, and courtship.

Detailed explanation-2: -BEHAVIORAL PLASTICITY. Animals can respond to environmental change in 3 key ways: disperse, adjust through phenotypic plasticity, or adapt through genetic changes ( Williams et al.

Detailed explanation-3: -The ability of an organism to respond to external stimuli is called sensitivity. For example, Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.

Detailed explanation-4: -A stimulus is a change in the internal or external environment.

Detailed explanation-5: -When a living thing responds to its environment, it is responding to a stimulus. A stimulus (stimuli, plural) is something in the environment that causes a reaction in an organism. The reaction a stimulus produces is called a response.
