1
Driving question: How does ecosystem deal with animal and plants after they died?
2
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
3
Three types of decomposers
Another decomposer – Invertebrates One common decomposer: Fungi Crucial decomposers: bacteria and microscopic fungi
4
The structure of mushroom
cap gill stem hypha mycelium Mycelium part should be bigger than mushroom Are mushroom plants?
5
Digestion part
6
How do mushrooms grow? Switch our focus from cap of mushroom to mycelium
