An organism's niche includes all of these except: a. the space an organism requires. b. the timing of an organism's reproduction
Viefleur [7K]

Answer:

c. the specific geographical location where an organism lives.

Explanation:

The ecological niche of an organism includes the habitat where it lives and its place in the community with respect to the other species. It includes various adaptations present in the organism to survive in prevailing conditions, its interaction with other biotic factors of the system, and the pattern of consumption of available resources. Therefore, the ecological niche of an organism defines the space occupied and its functional role in the community irrespective of the type of biome. It does not take account of its geographical location on the earth.
