kherson [118]

Answer:

B. Decrease to its carrying capacity

Explanation:

Goby fish feed over algae for their survival and growth but if 50% of algae in the ocean decreases then the population of goby fish will decrease to its carrying capacity.

This is so because then the goby fish will be dependent on the left number of algae and maximum population size will depend on the rest 50% of food or algae available.

Hence, the correct answer is "B. Decrease to its carrying capacity".

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.
