Some species, particularly those found in the order Saprolegniales, are saprotrophs and decompose both plant and animal material. Like producer and consumer, decomposer is also a part of the food chain on our planet. A separate trophic level, the decomposers or transformers, consists of organisms such as bacteria and fungi that break down dead organisms and waste materials into nutrients usable by the producers. Decomposers use the carbon dioxide in the bodies of dead organisms for food or fuel. Below is a massive list of ecosystem words - that is, words related to ecosystem. Aquatic insects are derived from various terrestrial ancestors that have secondarily invaded aquatic environments and therefore do not represent a distinct taxonomical unit within the class Insecta.
