QuestionNEET 2025

Which one of the following pairs is a biotic component of the ecosystem?

Answer & NCERT explanation

Correct answer: A Producers and consumers

Biotic components are living parts of an ecosystem. Producers (plants) and consumers (animals) are both living organisms that interact within an ecosystem. Soil is abiotic (non-living), temperature is abiotic, air and water are also abiotic components. According to NCERT, ecosystems have biotic (living) and abiotic (non-living) components.

You have already learnt in previous classes that Ecology is a subject which studies the interactions among organisms and between the organism and its physical (abiotic) environment.

How NTA Uses This Concept

Ecology fundamentally studies interactions between organisms (biotic) and their physical environment (abiotic). NTA tests whether students understand that ecology encompasses both biotic interactions (predation, competition, symbiosis) and abiotic factors (temperature, light, water). Students commonly mistake ecology as only studying individual organisms or only focusing on environmental factors, missing the interaction component. Remember: Ecology = Organism-to-organism interactions + Organism-to-environment interactions. This foundation is critical for NEET as all subsequent concepts (population dynamics, community interactions, ecosystem functions) build on understanding these relationships clearly.
