Answer: C. All of the resources a species uses within its ecosystem

In the field of ecology, a niche is defined as the specific function, quarters, or type of living of a species within an ecosystem. It can be defined as web of life that includes possible resources of species, for instance, food sources, shelter, and space, and also the environmental conditions a plant or an animal needs to fulfill its reproductive purpose.

This category includes the feature an organism fulfills in an ecosystem, i.e. the nutrients it uses, the place, and the type of interactions between the organism and others in the community. This ecosystem is the specific niche of the species where it is adapted to biotic and abiotic factors and so lives in.

Defining the niche of a species as the sphere of interactions for the use of resources within their ecosystem strengthens its ability to survive and reproduce in their surroundings.
