Question

Which statement best describes an ecological effect of swamps?

O The brackish areas favor many species maturation and mating.
O The location by the edge of lakes increases pollutants and sediments.
O They provide an environment for rivers to quickly pass through, depositing nutrients.
O The slow movement of waters promotes filtration of nutrients for the plants.

Answer 1

The statement that best describes an ecological effect of swamps is that the slow movement of waters promotes filtration of nutrients for the plants. Swamps serve as natural filters, trapping pollutants and providing nutrients through decaying plant material.

Step-by-step explanation:

Out of the options provided, the statement that best describes an ecological effect of swamps is: The slow movement of waters promotes filtration of nutrients for the plants.

Swamps, along with other wetlands like freshwater marshes and bogs, are characterized by slow and steady water flow. This allows swamps to serve as crucial natural filters, as they can trap pollutants and enhance the quality of water by removing excess nutrients through sedimentation and the actions of plant life. Moreover, the decaying plant material widely found in swamps provides rich nutrients back to the environment, acting as a natural cycling mechanism for organic matter.

Brackish areas typically refer to estuaries where fresh and salt water mix, not swamps. Swamps do not necessarily increase pollutants and sediments; instead, they can capture and neutralize them. While swamps do allow rivers to pass through, they are more characteristic of slowing down water flow and enabling nutrient deposition, rather than promoting rapid passage.
