Key Idea.
Section 1
Animals Form Groups to Meet Needs
Many animals live together in groups. This group behavior helps them meet their needs and survive in their environment.
Working together makes it easier to find food. Groups also provide protection from predators, which are animals that hunt other animals. With many members watching for danger, it is easier to spot a threat and warn others. This helps keep the whole group safe.
Section 2
Animals Form Groups of Different Sizes
Animal groups come in different sizes. Some groups are small, like a pride of lions. Other groups are huge, like a school of thousands of fish. The type of animal, or species, helps determine the group's size.
The size of a group also changes based on the animal's home, or environment. If there is a lot of food, the group can grow larger. The number of animals in a group can also help them stay safe from predators.
