Producers:- the green plants make their own food with the help of simple inorganic molecules like carbon and water which means they are not dependent on other for their food, even they provide for all other organisms that's why they are called produces.

Decomposers:- the producers are eaten up by other organisms and when those organisms died their remain stay on earth which are eaten up by small organisms which are called decomposers.

Green plants are called producers because they are able to produce their own food through the process of photosynthesis. They are the primary source of energy for all other living organisms on earth. Plants use sunlight, water and carbon dioxide to produce glucose, which is used as an energy source for the plant itself and other organisms that consume it.



Decomposers play a crucial role in the ecosystem as they break down dead organic matter, including dead plants and animals, and recycle the nutrients back into the soil. Without decomposers, dead organic matter would accumulate and nutrients would not be available for new plant growth.



There are many types of decomposers, including bacteria, fungi, worms, and insects. Bacteria and fungi are particularly important as they break down the dead matter into smaller molecules that can be absorbed by plants.



The decomposition process begins with detritivores, organisms that feed on dead organic matter and break it down into smaller pieces. This makes it easier for decomposers to access the dead matter and begin the breakdown process. Decomposers secrete enzymes that break down the organic matter into simpler molecules such as carbon dioxide, water and nutrients like nitrogen and phosphorus. These nutrients are then released into the soil where they can be taken up by plants.



Decomposers are essential for the proper functioning of the ecosystem. They help to maintain soil quality by recycling nutrients, which are then available to plants. In addition, they help to prevent the accumulation of dead organic matter, which can lead to the spread of disease and pests.



In conclusion, producers such as green plants are essential for the production of energy in the ecosystem, while decomposers play a crucial role in recycling nutrients and maintaining soil quality. Together, these two groups of organisms form the foundation of the food chain and help to maintain the delicate balance of the ecosystem.
