In an ecosystem, which organisms are responsible for decomposing organic material?

• A. Producers
• B. Consumers
• C. Decomposers
• D. Herbivores

Answer: (C)

Decomposers are crucial organisms in an ecosystem, responsible for breaking down organic material, such as dead plants, animals, and other organic waste. This process of decomposition recycles nutrients back into the soil, making them available for producers, such as plants, to use in their growth. By breaking down complex organic molecules into simpler compounds, decomposers help maintain the balance of ecosystems and facilitate nutrient cycling.

In an ecological context, producers are the organisms that create their own food through photosynthesis or chemosynthesis and do not play a direct role in decomposition. Consumers, which include herbivores, carnivores, and omnivores, obtain energy by consuming other organisms rather than decomposing them; they rely on producers for energy and organic material. Herbivores specifically focus on eating plants and do not engage in the decomposition process. Therefore, it is the decomposers that fulfill the vital role of recycling organic matter and ensuring the sustainability of the ecosystem.
