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

Inorganic matter
(H2O , CO2, minerals)

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. Cellular respiration part

6. How do mushrooms get energy for growth and cellular work?
