For matter to be recycled and returned to the food chain, decomposers must be present. Decomposers are the final link in a food chain. They play a very important role in the food chain and makes it a cyclic process. They eat up dead animals and plants and produce nutrients from these matter back to the food chain. Plants needs nutrients for growth while living animals take up the nutrients they need from eating plants. The nutrients from these living organisms are recycled back to the ecosystem when they die by the process called decomposition with the help of decomposers.
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
