lord [1]
<h2>Competitive exclusion principle.</h2>

Explanation:

The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.

All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.

Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.

<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.
