6 CO2 + 6 H2O –> C6H12O6 + 6 O2
2

3
Q
Trophic levels (from bottom of pyramid to top)
A
producers, primary consumers, secondary consumers, tertiary consumers
4
Q
How much energy is left as you move from one trophic level to another?
A
10% left
5
Q
What energy powers an ecosystem?
A
the sun
6
Q
How does the law of conservation of mass relate to the cycling of carbon through a food web?
A
when carbon is converted- say from glucose to carbon dioxide, the total mass is never lost; it just changes state
7
Q
Equation to find the net primary productivity
A
NPP= GPP - R
8
Q
food web
A
multiple food chains in one
9
Q
