decomposer
含义: An organism, typically a bacterium or fungus, that breaks down dead organic matter into simpler substances.
Decomposers are essential to all ecosystems, recycling nutrients from dead organisms and waste back into the soil and atmosphere. They differ from detritivores in that they break down matter externally through enzyme secretion rather than ingesting it. Without decomposers, nutrients would remain locked in dead matter. It collocates with 'fungi,' 'bacteria,' 'matter,' and 'nutrient.'
