a. water.
b. plants.
c. sunlight.
d. dissolved oxygen.

The correct answer is B. Plants

Explanation:

To begin with, in an ecosystem, factors can be classified into biotic factors if they are living organisms such as plants or animals or abiotic factors if they are physical or non-living factors. This means, in the case of a swampt the most importan biotic or living factors would be plants due to the prevalaence of aquatic vegetation in this ecosystem but also other such as animals are part of this. On the other hand, water, sunlight and dissolved oxygen are abiotic rather than biotic factors as they are part of this ecosystem but do not have life. Thus, the most important biotic factor in a swamp is plants.
