Why do animals form groups?

Answer

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.

Question

How do groups help animals to survive?

Answer

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.

Question

Meerkats live in large families. Some are look-outs while others care for the young. Other meerkats are in charge of digging tunnels, and some are hunters. The meerkats will trade jobs and take turns.

Meerkat, Herd, Meerkats, Group, Rodents

Why does living in this large family benefit the meerkats?

Answer

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.

Question

Elephants live in large herds. When traveling, they keep the babies in the middle of the line or center of the group.

Elephant, Serengeti, National Park

How do these large groups help babies survive?

Answer

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.

Meerkats live in large families. Some are look-outs while others care for the young. Other meerkats are in charge of digging tunnels, and some are hunters. The meerkats will trade jobs and take turns.

Meerkat, Herd, Meerkats, Group, Rodents

What could happen to the meerkats if they started living alone instead of in groups?

Answer

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. If the meerkats were forced to live alone rather than in family groups, they might die. If they are busy gathering food or digging tunnels, they may not see predators. It would be hard for a meerkat to do all of the jobs by itself.

Question

Which answer choice(s) is a benefit of animals forming groups?

Answer

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.

Question

Monkeys live in family groups that can grow quite large in numbers. If monkeys lived alone, there are some tasks they could not complete. Based on the photo below, what is a task that requires a group to help with?

Berber Monkeys, Ape, Delouse, India

Answer

Monkeys are very social and live in large groups with extended family. Monkeys help each other groom and use it as a chance to spend time with each other. Without a group to help the monkeys could not groom themselves properly. They rely on each other for help with their survival needs.

Answer

Living in groups provides animals with many benefits.

Working together provides them with more opportunities for survival than living alone does. Animals often fare better when living together than those outcasted to living alone.

Fish are one of many animals who form groups for survival. They will form "bait balls" with hundreds (even thousands) of fish to scare away predators and make it more difficult for predators to catch them.

School, Fish, Underwater, Tropical

Why would it be better for a fish to join the "bait ball" rather than swim alone?

Answer

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. If a fish is swimming alone, it stands out and is more likely to be chased and eaten. When the fish are in a group, their chances of being singled out and eaten are decreased, and many times the large gathering of fish scares the predators off completely.
