Phytoplankton receive energy through photosynthesis. Photosynthesis is the process of making glucose using sunlight. Carbon dioxide, sunlight, and water combine, producing gluâ¦cose sugars that the being can use for energy.  Zooplankton however feed off phytoplankton and decaying matter. They are known as detrivores.
Rating Newest Oldest. Best Answer: Energy transfer as you go up the trophic levels is not 100%. Actually, 10% efficiency is a lot closer. Therefore, it takes about ten times the food input to increase the weight of an animal, say 10# of grass to produce 1# of beef.DDT is not excreted by the organism; it is sequestered in the fatty tissue.he DDT on the wheat is picked up by the grasshoppers and stored. They have to pick up quite a bit in order to grow because of the 10% efficiency of energy transfer. The same concentration goes on as you go up a trophic level or two to the hawks.
