What are biotic factors, and how do they influence a community?

Biotic factors are the living components of an ecosystem that can affect the community, such as plants, animals, and microorganisms. They influence community dynamics through interactions like competition, predation, and symbiosis, which can impact population sizes and species distribution.

This answer is strong because it clearly defines biotic factors and provides examples of their influence on a community. The question tests the student's understanding of the concept and its implications in ecological interactions.
