Which describes a disadvantage of social behavior?

Foraging could increase competition for food.

Mating with more than one mate could increase reproduction rates.

Members of the group may not have to do as much work to survive.

When animals form groups, it could be more difficult to distract predators.

Of the four options, the option: 'Mating with more than one mate could increase reproduction rates' would not be a disadvantage for the species. A higher reproduction rate generally ensures the survival of the species. The option 'Members of the group may not have to do as much work to survive' is also not a disadvantage, and it is true that animals that live in social groups can cooperate to forage and hunt. The option 'when animals form groups, it could be more difficult to distract predators ' is not true. Many animals form groups exactly because it lowers the probability of a single individual becoming prey. Think for example of zebra. The patterns of large groups of zebra are very confusing to predators. Large troops of monkeys can also cooperate to make it difficult for predators to hunt. So the option: ' Foraging could increase competition for food' is the correct answer in this case. Consider that large groups of animals all foraging on a common food source will more quickly deplete the food source. More dominant members in the group may claim more food than the other members.

The answer is B in short for that other guy
