Which term refers to living elements of an ecosystem?

• A. Biotic
• B. Abiotic
• C. Chemotactic
• D. Inert

Answer: (A)

Biotic refers to the living components of an ecosystem—plants, animals, microorganisms, and the interactions among them. In a turf system, that includes the turfgrass itself, insects and beneficial organisms, and disease-causing microbes. Abiotic describes the non-living parts like air, water, temperature, light, and minerals. Chemotactic is about movement toward or away from chemical signals, a behavior, not a category of living components. Inert means non-reactive or non-living, which doesn’t capture the living elements of an ecosystem.
