If decomposer populations were to decline, what would be a likely environmental consequence?

If decomposer populations were to decline, a likely environmental consequence would be the accumulation of dead organic matter. Decomposers, such as bacteria and fungi, play a crucial role in breaking down dead plants, animals, and organic waste. They recycle nutrients back into the ecosystem, which is essential for soil health and plant growth.

With fewer decomposers, the rate of decomposition slows significantly, leading to a build-up of organic materials that would normally be broken down and utilized by other organisms. This accumulation can hinder the availability of nutrients for plants and other organisms, ultimately impacting the overall health of the ecosystem. The presence of excess dead organic matter can also affect soil oxygen levels and create an environment that is less conducive to plant growth and nutrient uptake. Thus, the decline in decomposer populations directly correlates with the accumulation of dead organic matter in the environment.
