Gross primary productivity, or gpp, is the rate at which solar energy
is captured ih glucose molecules during photosynthesis. producers
such as plants use some of this energy for metabolism and some for
growth. energy is transferred between trophic levels when one
organism eats another. however energy transfers are never 100%
efficient. therefore, each trophic level has a successively smaller
energy pool from which it can withdraw energy. determine the
amount of energy for the spiders, a secondary organism in the food
chain if the gross primary production (gpp) starts at 2,500,000 j of
energy
