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

What is the difference between the conducting zone and the respiratory zone of the respiratory system? the conducting zone is a series of cavities and tubes that move air to the respiratory zone where gases exchange with the bloodstream. the conducting zone exchanges gases between the lungs and the alveoli and the respiratory zone is a series of cavities and tubes that move air to the conducting zone. the conducting zone moves oxygen into the cells and the respiratory zone takes carbon dioxide away from the cells. the conducting zone moves oxygen into the bloodstream and the respiratory zone takes carbon dioxide away from the bloodstream.
