Answer:
Group behavior, also known as collective behavior, <u>can increase the chances for a species to survive and reproduce because they can rely on each other to accomplish behaviors that are crucial for their survival, such as hunting, migrating, and breeding.</u>
Explanation:
According to ethologists, social species highly depend on the members of their own group for survival. One perfect example is the case of <u>schooling fish</u>. These small species of fish gather in a whole large group and navigate long distances while looking for food. Researchers from Princeton University <u>discovered that their orientation capabilities increased when more individuals joined the group, making them more responsive to the environment.</u>
<u />
Moreover, there have been numerous sources of evidence that demonstrate that <u>orcas (killer whales)</u><u>,</u> which are extremely social creatures<u>, create large pods of around 20 to 30 individuals and 'plan' strategies to hunt. Also, older females swim along younger individuals to teach them hunting skills that are crucial for their survival.</u>
<u />
In addition, <u>herbivores</u>, like zebras, <u>are usually found in large groups because it lowers the possibilities of being individually targeted by apex predators, such as lions.</u>
<u />
Recently, researchers have also discovered that <u>migrating species</u><u> often rely on each other to improve their migrating capabilities by producing or generating social cues that allow them to improve their orientation or in cases when environmental conditions get tough</u> (Source).
In conclusion, these lines of evidence show that social organisms who travel in groups rely on all members to carry out important behaviors that, without them, would provoke an important decline in their populations because they wouldn't be able to reproduce or feed individually as successfully as they would with the 'help' of the members of the group.
