There are two kinds of decomposers, Decomposers get energy through respiration, so they are heterotrophs. In fact, it is estimated that there are billions of bacteria in one gram of soil. Flies, slugs, beetles, ants, and worms are very important decomposers. What Kind of Bacteria are Decomposers in the Ocean? . [1] Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development. Plant growth would decrease over time as the nitrogen the plants took from the soil was not replaced. For example, bacteria are used to ferment yogurt, cheeses, and sour cream. They are found within the soil and they feed on organic matter present throughout multiple layers of the soil. algae, cyanobacteria and the decomposers, play as primary producers and in the cycling of nutrients. Decomposers are being used in some wastewater treatment plants to make the water we have used in our homes clean and ready for human consumption again.
