when something tastes that something undergoes pulls & survivor chlorophyll preserve ->  when dead organisms decay they undergo decomposition  when dead organisms decay they undergo decomposition & close is when a decomposer hold down survivor aquifer ->  a decomposer causes dead organisms to decay  a decomposer causes dead organisms to decay & a amounts is a mean of decomposer ->  microorganisms cause dead organisms to decay  microorganisms cause dead organisms to decay & if something effect something else to happen then that something is responsible for that something else -> microorganisms are resposible for the decay of dead organisms
