The most abundant species in a community is called the

a. apex competitor

b. dominant species

c. alpha species

d. keystone species

e. top predator

b. dominant species

Explanation:

Dominant species in an ecological community is the one that is present in profuse number. Due to their abundance, they affect the presence, distribution, and abundance of other species of the community.

For example, trees are dominant species in the forest ecosystem and regulate the occurrence of other species on the forest floor by affecting the availability of light and moisture.

Option (B)

Explanation:

Dominant species are those that are found to exist abundantly in any specific type of ecosystem. It generally reflects the highest amount of densely populated groups of species that significantly form a large biomass in an ecosystem. It also affects the occurrence and the scattering of these species.

The dominant species acquire most of the resources that are available in an ecosystem and are the strongest. These dominant species differ from one ecosystem to another. For example, the dominant plants in any type of forest ecosystem are the trees.

Thus, the correct answer is option (B).
