Bacteria play a vital role in the decomposition process, breaking down organic matter and recycling nutrients back into the ecosystem. They facilitate the mineralization of complex compounds, transforming them into simpler substances that can be utilized by plants and other organisms. This microbial activity promotes soil health and fertility, ensuring that ecosystems function efficiently. Moreover, bacteria are essential in biogeochemical cycles, such as the nitrogen and carbon cycles, supporting overall ecosystem stability and productivity. Their role in decomposition underscores the interconnectedness of life within various environments.
