Correct option is A
Answer(a). Ecological niche
Ecological niche
Explanation: An ecological niche refers to the role and position of a species in its environment, which includes how it interacts with both biotic (living) and abiotic (non-living) factors. It encompasses the species' habitat, its interactions with other species (such as predation, competition), and how it adapts to the environment's resources and conditions. In essence, it defines how a species fits into its ecosystem.
Reason for selection: The ecological niche describes the interaction of a species with all the biotic and abiotic factors affecting it.
Food web
A food web is a network of interconnected food chains in an ecosystem, showing how energy and nutrients flow between organisms. It primarily illustrates feeding relationships, not the complete interaction of a species with its environment.
Reason for exclusion: A food web only deals with feeding relationships, not the full range of interactions with biotic and abiotic factors.
Food chain
A food chain is a linear sequence of organisms where each organism is eaten by the next one in the chain. It shows how energy flows from producers to consumers. However, it does not encompass all the ecological factors affecting a species.
A food chain focuses on energy flow and feeding interactions, not the broader environmental interactions of a species.
Natural habitat
A natural habitat refers to the physical place where a species lives, which provides the conditions it needs to survive (like food, shelter, and mates). However, a habitat alone does not fully capture all the interactions a species has with its environment, especially the biotic and abiotic factors.
While a habitat provides the living space for a species, it does not define the full interaction between the species and all environmental factors.
