Question

which best describes what happens when an animal does not form a social group? foraging is more difficult when hunting a large prey. reproduction is easier because of access to multiple mates. fighting off predators is easier with one individual. the division of labor is more difficult as it increases competition.

Explanation:

Social - grouping in animals often provides advantages like easier foraging for large prey through cooperation. Without a social group, foraging for large prey becomes more difficult. Reproduction is usually more challenging without group - access to mates. Fighting off predators is harder alone. Division of labor is a benefit of social groups, so lack of it doesn't increase competition in the context of division of labor.

Answer:

Foraging is more difficult when hunting a large prey.
