Which term means Non-living things?

• A. Abiotic
• B. Benign
• C. Analgesia
• D. Abatement

Answer: (A)

Non-living things in an environment are described as abiotic. The prefix a- means not, while biotic refers to living organisms, so abiotic covers the non-living factors that shape ecosystems, like sunlight, temperature, rainfall, soil minerals, pH, and salinity. These elements influence how organisms survive, grow, and interact, even though they aren’t living themselves. The other terms describe different ideas: benign means harmless, analgesia refers to the loss of pain sensation, and abatement means a reduction or decrease of something, not a category of non-living environmental factors.
