Why could only 4 % of the energy from sunlight be fixed by producers during photosynthesis?
1 )
A lot of energy is lost as energy passes from one trophic level to the next in food chains.

3 )
Some energy passes from dead plants to decomposers such as bacteria and fungi.
4 )
Some parts of plants are not eaten or cannot be digested by herbivores.
