1. Calculate the amount of energy available for the following food chain, assuming 178,000 kJ per m^2 per year is contained in the primary producers (assume a 10% transfer efficiency for each level).
Energy Transfer Calculation Practice
1. Calculate the amount of energy available for the following food chain, assuming 178,000 kJ per m^2 per year is contained in the primary producers (assume a 10% transfer efficiency for each level).
a. Primary consumer -
b. Secondary consumer -
c. Tertiary consumer -
d. Quaternary consumer –
2. For the above food chain, compare the biomass of the primary producers to that of the tertiary consumers. Why is there a difference?
3. For the following questions refer to the following food chain (show your work):
Smelt
1250 kJ m-2 year-1
Algae
42000 kJ m-2 year-1
Human
50 kJ m-2 year-1
Small aquatic animals
6 300 kJ m-2 year-1
Trout
250 kJ m-2 year-1
Primary consumers and secondary consumers
Tertiary consumers and quaternary consumers
Producers and quaternary consumers
