What environmental factors determine the composition of a community?

The composition of a community is influenced by several environmental factors, including climate, soil type, topography, and availability of water. Climate determines the temperature and precipitation patterns, which affect the types of plants and animals that can thrive in a region. Soil type influences nutrient availability and moisture retention, while topography can create microhabitats that support diverse species. Additionally, human activities, such as land use and pollution, can significantly alter community composition.
