Detailed explanation-1: -The term niche is used to describe the role an organism or population plays within its community or ecosystem. It encompasses all relationships that the organism (or population) has with its environment and with other organisms and populations in its environment.
Detailed explanation-2: -Complete answer: The functional status of an organism in its community is termed as an ecological niche. The term ecological niche tells the position of a species within an ecosystem, it also describes the range of conditions necessary for the persistence of the species and their role they perform in the ecosystem.
Detailed explanation-3: -So the correct option is ‘niche’.
Detailed explanation-4: -Ecological niches are important for species, as they allow them to function without high competition for shared, limited resources. Often we can observe the true importance of ecological niches for an ecosystem only when the species occupying it ceases to exist in it.
Detailed explanation-5: -The functional role of any species in an ecosystem or community is referred to as the niche. Niche describes how the species interact with the biotic and abiotic components of the ecosystem. Thus, each organism has an invariably defined range of conditions that it can tolerate.
