decomposers are essential to an ecosystem because they:
break down dead organisms and return nutrients to the soil
regulate the population of primary consumers
produce oxygen through photosynthesis
convert inorganic matter to organic matter

This process releases nutrients such as nitrogen, phosphorus, and potassium back into the soil, which are then available for plants to use. This nutrient - cycling is crucial for the health and functioning of an ecosystem.
