Decomposers are organisms that break down dead organic material. This process is essential for nutrient cycling in ecosystems. They consume dead plants, animals, and waste products, returning vital elements like carbon, nitrogen, and phosphorus back into the soil and atmosphere. Without decomposers, these nutrients would remain locked up in dead matter, making them unavailable for living organisms.

Common decomposers include bacteria and fungi. Bacteria are microscopic single-celled organisms found in virtually all environments. Fungi, such as mushrooms and molds, are multicellular organisms that secrete enzymes to break down complex organic molecules externally before absorbing them. Other organisms like earthworms and certain insects also play a role in decomposition by fragmenting dead material, which increases the surface area for bacteria and fungi to act upon.

The activity of decomposers is influenced by environmental factors such as temperature, moisture, and oxygen availability. For instance, decomposition rates are typically higher in warm, moist conditions with plenty of oxygen. In arid or frozen environments, decomposition can be significantly slower. This breakdown process not only recycles nutrients but also cleans up the environment by removing dead bodies and waste.
