Detailed explanation-1: -More importantly, decomposers make vital nutrients available to an ecosystem’s primary producers-usually plants and algae. Decomposers break apart complex organic materials into more elementary substances: water and carbon dioxide, plus simple compounds containing nitrogen, phosphorus, and calcium.
Detailed explanation-2: -Through decomposition, nutrients stored in the dead material re-enter the system and act as a natural fertilizer for plants throughout the year. The controls and nutrient cycling are especially important for forest wildflowers.
Detailed explanation-3: -During the decomposition process, microorganisms convert the carbon structures of fresh residues into transformed carbon products in the soil. There are many different types of organic molecules in soil. Some are simple molecules that have been synthesized directly from plants or other living organisms.
