Approximately 10% of the energy absorbed by one

trophic level is transferred to the next successive

level. The same number of calories are available at

the primary producer level of each of these food

chains.

Food Chain 1:

phytoplankton → zooplankton → smelt → trout → humans

Food Chain 2: phytoplankton → smelt → humans

How much energy is available to humans in

Food Chain 2 as compared to the energy available

to humans in Food Chain 1?

(look at the difference in trophic levels)

A) 100 times less energy

B) 10 times more energy

C) 100 times more energy

D) 10 times less energy
