Which type of organism plays a key role in the decomposition process in ecosystems?

Detritivores are essential in the decomposition process within ecosystems. They specialize in breaking down dead organic material, such as plant debris and animal remains, which contributes to nutrient cycling. By consuming this detritus, detritivores help to convert complex organic matter into simpler forms, making nutrients available to plants and other producers in the ecosystem. This process enriches the soil, promoting growth and maintaining the balance of the ecosystem.

Herbivores primarily feed on living plants and do not contribute directly to the breakdown of dead organic matter. Carnivores consume other animals but typically do not play a direct role in decomposition either. Producers, which include plants and photosynthetic organisms, are involved in creating organic matter but do not decompose it. Thus, the unique role of detritivores in breaking down and recycling nutrients positions them as key players in the decomposition process.
