hi my name is noela. I am in the 5th grade. My teacher just taught us about why two similar species cannot have the same niche.

The reason is.........................................................................................

Two similar species cannot have the same niche because in order to have the same niche those two species would have to have to be identical. But no to species are identical so no to species can have the same niche. in order for it to be identical those two similar species would have to eat the same food, be eaten by the same predators, they would have to live in the same area, they would have to reproduce in the same ways, they would have to grow under the same temperature etc. etc.

They would outcompete each other for access to food and resouces.

This is the Theory of Competitive Exclusion. The limited resources in an ecosystem must be partitioned between two species in some way otherwise they would be competing "head to head" for all their life's needs, and this would be a serious waste of their energy.

Two species can occupy the same niche. Interspecific competition is responsible for the resulting relative abundances (# of each organism) in the community.
