Final answer:
Living in a group can affect competition within the same species as well as between different species.
Step-by-step explanation:
Living in a group can affect competition with members of the same or other species in several ways.
When individuals of the same species live in a group, they may compete for limited resources such as food, water, or territory. This is known as intraspecific competition. For example, a group of lions may compete for the same prey, and the individuals that are better adapted or more skilled at hunting will have a higher chance of obtaining food.
Living in a group can also impact competition with members of other species, known as interspecific competition. In this case, different species may compete for the same resources. For instance, if a group of birds and a group of squirrels both rely on the same food source, they may compete for it. The species that is better adapted to utilize or obtain that resource will have a competitive advantage.
