Respuesta :
Group behavior is also known as collective behavior, which increases the chances of species to reproduce and survive because they rely on one another to carry out actions essential for their survival like hunting, migration, and breeding.
Ethologists claim that social organisms rely heavily on other group members to survive.
The basic example of group behavior is a school of fish. These little fish species congregate in huge groups and travel great distances in search of food. When more people joined the group, researchers from Princeton University found that their ability to maintain orientation improved, making them more receptive to their surroundings.
Moreover, there are many pieces of evidence that show orcas (killer whales), which are highly sociable animals, form big pods of 20–30 people and 'plan' their hunting techniques. Younger individuals are also taught essential hunting techniques by older females who swim with them.
Conclusion: Social organisms that travel in groups rely on all members to carry out crucial behaviors that, if they didn't, would cause a significant decline in their populations because they couldn't feed or reproduce as successfully on their own as they could with the group's "help."
