What is the role of Paramecium in the enviroment?

Answer 1

Paramecium and other microscopic biota feed on organic matter in their environment and break it down into smaller particles or convert the organic matter into energy for themselves. Some biota are helpful in breaking down organic matter in soils into nutrients in a form that is easier for plants roots to absorb or take up to feed the plants. Some biota convert nitrogen in the water and air into a form of nitrogen that can be absorbed by plants roots. Paramecium and other aquatic biota break down all kinds of organic and chemical matter and use it as food for themselves with their output being smaller molecular particles and carbon dioxide. The small aquatic biota are food for larger creatures such as very small fish, shrimps, and aquatic insects. Those creatures are food for bigger fish, and we sometimes eat the species that feed on the small fish and insects that feed on the paramecium and other biota. It's all part of the cycle.
