How do composers interact with their ecosystem

Composers or consumers eat the by-product of plants in order to get proper nourishment and development. Their waste excretions are in the soil which nourishes it. This is also used by the plants as producers in order to produce more food for the consumers. When consumers die, they become food for the decomposers such as worms, fungi, bugs, and ants so consumers help them to thrive. In the process, the soil becomes nourished of the mineral breakdowns from the body of the consumers, this is again used by producers to provide healthy and nourished foods.
