A niche involves both abiotic and biotic factors.
- Biotic factors refer to the living components of an ecosystem, such as plants, animals, fungi, and microorganisms, and their interactions.
- Abiotic factors are the non-living components, including climate, soil, water, and nutrients.
In ecology, a niche describes how an organism or species interacts with both types of factors in its environment. Therefore, the correct choice is Both.
