Driving question: How does ecosystem deal with animal and plants after they died?

Flow chart of decomposing process Dead plant/animal (large organic molecules) Minerals (from soil) Flow chart of decomposing process Digestion Digestion Inorganic matter (H2O , CO2, minerals) Small organic molecules Biosynthesis Back to ecosystem system Decomposer biomass (large organic molecules) Cellular Respiration Fungi take in minerals from soil, like plants  Revised it H2O & CO2 For decomposers growth For decomposers living

Three types of decomposers Another decomposer – Invertebrates One common decomposer: Fungi Crucial decomposers: bacteria and microscopic fungi
