Which term describes the living components of an ecosystem?

• A. Biotic
• B. Abiotic
• C. Nutrient
• D. Energy

Answer: (A)

Living components of an ecosystem are described by biotic factors—the organisms themselves and their interactions. This includes plants, animals, fungi, bacteria, and any other living things involved in the ecosystem's processes. Abiotic factors are the nonliving parts, like sunlight, temperature, water, and soil. Nutrients are the chemical substances organisms need to survive, but they are not living. Energy describes the capacity to do work that flows through the system from one organism to another, not a living component. Therefore, biotic best describes the living components.
