In ecological terms, which term describes living components?

• A. Biotic
• B. Abiotic
• C. Autotrophic
• D. Heterotrophic

Answer: (A)

Biotic describes the living components of an ecosystem—the organisms themselves and their interactions, such as plants, animals, fungi, and microorganisms. Abiotic refers to nonliving parts like climate, soil, moisture, and light. Autotrophic and heterotrophic describe how organisms obtain energy or food, not whether they are living or nonliving. Since the question asks for the term that describes living components, biotic is the best fit because it specifically denotes life forms and their relationships within the ecosystem.
