Basic needs are things that people need to survive. In order to survive, people require food, water, shelter, and clothing. Though schooling is an important benefit to help people be successful, it is not needed for survival.

Animals form groups to increase their chance of survival. The animals work together to hunt, raise their young, protect each other, and more. Survival would be much more difficult if some animals lived on their own rather than in a group.

Living in a large family benefits the meerkats because they can split up the work and have members of the family working together to keep the family safe and healthy. Rather than all of the work falling on a few animals, it can be split up amongst dozens. Living in large groups like this help with protection, food collection, and general survival.

Large herds of elephants can be seen moving across the plains of Africa with their babies in the middle of the group's lines as they travel. If predators attack them, the babies are usually targets because they are smaller and weaker. If the female elephants keep them hidden and guarded, they are protected. This technique is to help babies survive.

Fish form these "bait balls" to distract their predators and make it more difficult for them to be eaten. This technique is all about survival. Forming groups makes each fish safer than if they were swimming alone.

Living in groups provides animals with many benefits. A large group of animals is less likely to be bothered by predators, there are more females to care for and protect the young, and more members to look for food sources. Working together provides them with more opportunities for survival than living alone does.

All of the answer choices list a benefit to animals forming groups. When animals form groups for survival, they can help each other raise the young, hunt, keep watch, gather food, find shelter, and survive. Animals in groups have more eyes looking for predators or prey. They also have less work to do individually because they can share the workload. Animals in groups often survive better than if they lived alone.
