Detailed explanation-1: -Animal behavior includes all the ways animals interact with other organisms and the physical environment. Behavior can also be defined as a change in the activity of an organism in response to a stimulus, an external or internal cue or combo of cues.

Detailed explanation-2: -Instinct, imprinting, conditioning, and imitation are the four types of animal behavior.

Detailed explanation-3: -Animals communicate using signals, which can include visual; auditory, or sound-based; chemical, involving pheromones; or tactile, touch-based, cues.

Detailed explanation-4: -One example of how social behavior is adaptive is aggregation against predators. This concept applies to caterpillars feeding together on a leaf, a herd of wildebeest, schools of fish, and flocks of birds. A landscape filled with solitary wildebeest will offer easy pickings for large predators such as lions (Figure 2).
