Decomposition is the process by which organic substances are broken down into simpler organic or inorganic matter. This process is fundamental to nutrient cycling in ecosystems. It involves the breakdown of dead organisms, such as plants and animals, and their waste products.

The primary agents of decomposition are microorganisms like bacteria and fungi, along with detritivores such as insects and earthworms. These organisms consume the dead organic material, extracting energy and nutrients for their own survival. In doing so, they convert complex organic compounds into simpler substances like carbon dioxide, water, and mineral nutrients.

Decomposition rates can vary significantly depending on environmental factors. Temperature, moisture, and the availability of oxygen are key influences. Warmer, moist conditions with ample oxygen generally lead to faster decomposition, while cold, dry, or anaerobic environments slow the process considerably.

The products of decomposition are vital for sustaining life. Released mineral nutrients, such as nitrogen and phosphorus, become available in the soil for uptake by plants, forming the base of new food chains. Carbon dioxide released into the atmosphere is used by plants during photosynthesis.

In essence, decomposition is a continuous natural recycling process that prevents the accumulation of dead organic matter and ensures the availability of essential elements for living organisms.
