How would the environment be different without decomposers?

Without decomposers, the environment would be significantly altered, as organic matter from dead plants and animals would accumulate, leading to a build-up of waste. Nutrient cycling would be disrupted, resulting in depleted soil fertility, which would adversely affect plant growth and agriculture. Ecosystems would struggle to maintain balance, as essential nutrients would remain locked in dead matter, ultimately impacting all levels of the food chain. This could lead to reduced biodiversity and increased competition among species for limited resources.
