Definition of “Ecosystem” by Modern Ecologists

January 17, 2019 0 Comment

Community trophic structure consists of grazer system alongside a decomposer system. Subcompartments are recognized within each trophic level so that distinctions are made between invertebrates and vertebrates and between microbes and detritivores.

Energy consumed and assimilated by living organisms, some of which is lost from the system as respiratory heat during work. Possible pathways in grazer and decomposer system are same except that feces and dead bodies lost to decomposer system are simply sent back to dead organic matter pool. Energy available as dead organic conditions are unfavourable to decomposition process, leaving incompletely metabolized high energy matter, such as, oil, coal and peat.
