Bacteria are important to ecosystems because they act as decomposers to digest dead organic remains and return inorganic nutrients to producers.
What are decomposers ?
Decomposers are organisms that disintegrate rotting or dead species; they carry out decomposition, a process only some kingdoms, like fungi, are capable of. Decomposers, like herbivores and predators, are heterotrophic, which means that they obtain their energy, carbon, and growth-supporting nutrients from organic substrates.
Microorganisms called decomposers break down complex organic components into less complicated inorganic substances that are absorbed into the soil. These species, such as bacteria and fungi, are examples. These inorganic elements are then recycled by plants.
Without decomposers, the planet would be littered with dead bodies, hence they are regarded as being of utmost importance.
