What role do decomposers play in the nutrient cycling process?

Decomposers play a crucial role in the nutrient cycling process by breaking down organic matter, such as dead plants and animals, as well as waste products. This breakdown process involves various microorganisms, fungi, and invertebrates that convert complex organic materials into simpler substances. As they decompose matter, these organisms release nutrients back into the soil, making them available for uptake by plants and other organisms. In this way, decomposers facilitate the recycling of essential nutrients like nitrogen, phosphorus, and carbon, which are vital for sustaining life and maintaining ecosystem health. Without decomposers, the accumulation of dead organic material would inhibit nutrient availability and disrupt the balance of ecosystems.
