Question

The feeding relationships among the species in a community determine the community's

(A) secondary succession.

(B) ecological niche.

(C) species richness.

(D) trophic structure.

Short answer

1. The option "secondary succession" isfalse.

2. The option "ecological niche" isfalse.

3. The option "species richness" is false.

4. The option "trophic structure" is true.

Step-by-step solution

Community

In ecology, the social unit of interacting living organisms with specific common characteristics in a geographical area is called community.

Explanation of option '(A)'

The form of ecological succession in which changes occur in habitat due to the replacement of a damaged community by new inhabitants is called secondary succession.

Thus, the secondary succession is related to the re-colonization of organisms in an area.

Therefore, the given option is false.

Explanation of option '(B)'

When species utilize abiotic and biotic resources that determine their functional role in their natural environment, it is called an ecological niche,

Thus, the ecological niche is associated with the species that exist in the environment.

Therefore, the given option is false.

Explanation of option '(C)'

In evolutionary biology and ecology, the term species richness represents the count of species living in a defined area, such as an ecological community.

Thus, the species richness does not take into account the feeding relationship.

Therefore, the given option is false.

Explanation of option '(D)'

The way that shows the pattern of organisms' arrangement at different trophic levels based on their energy consumption is called a trophic level.

Thus, the trophic structure deals with the trophic level that shows the resource consumption by organisms in a food chain and represents their feeding relationship.

Therefore, the given option is true.
