AP BIOLOGY

Detailed explanation-1: -Individuals living in large groups may be safer from attack because the predator may be confused by the large group size. As the group moves, the predator has greater difficulty targeting an individual prey animal.

Detailed explanation-2: -Most of the animals live in groups to protect each other from harsh climatic conditions, defend themselves against enemies, look for food or for possible mates. They help each other to bring up their offspring and learn from each other.

Detailed explanation-3: -Camouflage, highly developed senses, warning signals, and different defensive weapons and behaviours are all used by prey animals for survival. Camouflage is an adaptation in which a species evolves to resemble its background.

Detailed explanation-4: -Living in groups can allow collective defense of the group to stop predation by predators that may otherwise be too dangerous for a single individual to defend themselves (or their offspring) against alone.
