What is the primary role of bacteria in the decomposition process?

The primary role of bacteria in the decomposition process is to facilitate the breakdown of organic matter. Bacteria are essential decomposers in ecosystems, as they break down complex organic materials from dead plants and animals into simpler substances. This process not only leads to the recycling of nutrients back into the ecosystem but also plays a vital part in enriching the soil and making nutrients available for other organisms, such as plants.

During decomposition, bacteria metabolize organic materials, leading to the release of energy and contributing to the formation of humus, which improves soil structure. This breakdown is crucial for maintaining ecological balance and health, making bacteria indispensable players in the decomposition process.

While other options mention various biological roles, they do not encapsulate the essence of what bacteria primarily accomplish in decomposition, which is a fundamental ecological function.
