Final answer:
Saprobes, Consumers, and Omnivores are heterotrophs that play important roles in the ecosystem by feeding on decaying matter, relying on other organisms for food, and consuming both plants and animals.
Explanation:
Organisms that feed on decaying organic matter are known as saprobes. These organisms play a vital role in the ecosystem by breaking down dead organic material into simpler substances that can be recycled back into the environment.
