What term describes the biological influence on organisms within an ecosystem?

• A. Biotic Factors
• B. Abiotic Factors
• C. Predation
• D. Competition

Answer: (A)

Biotic factors refer to the living parts of an ecosystem—the organisms present and how they interact with each other. These living influences include predation, competition, symbiotic relationships, and decomposition, all of which affect survival, reproduction, and resource use. Abiotic factors are nonliving conditions like temperature, rainfall, and soil, which also shape ecosystems but are not biological. So the overall term for the living influence on organisms in an ecosystem is biotic factors.
