Ecosystem Energy Flow and Efficiency

Description
Main oceanic producers
Marine algae
Plants
Bacteria
Bacteria-like archaea
Only a small percentage of the energy taken in at any level is passed on to the next

Trophic levels
Chemical energy stored in the mass of the ocean’s algae is transferred to the animal community mostly through feeding  
Each feeding stage is called a trophic level
Transfer of energy between trophic levels is very inefficient (about 2 percent)
