how much energy is lost as it passes from esch trophic level
Homework Answers
During tranfer of one tropic level to next tropic level approximately 90% energy list , only 10% is transferred one next tropic level.
Explanation-
In ecosystems plant capture the solar energy and form food. This stired energy in firm of food taken up by consumers ( primary, secondary and tertiary consumer). As we go to each tropic level, 6ranfer of energy decreased. During flow to each tropic level only 10% energy is transferred to one tropic level to next tropic level. Rest 90 % of the energy lost in form of various process ( respiration, dead remain etc.) . It is the reason why food chains are found maximum to 4 or 5 tropic level. Because only 10 % of energy transferred fro one tropic level to next so when it reaches to 4 tropic level. Less energy remains that it can transfer this small amount of energy to next level.

Explain what happens with the total energy of the system at different trophic levels, indicating how much energy is transferred from one level to the next. Add a pesticide to your food chain and explain what happens with certain persistent chemical residues at different trophic levels.

Click in the answer box to activate the palette. Trophic-level transfer efficiency is the proportion of energy that is transferred from one trophic level to the trophic level directly above and used for biomass production. For example, if we consider a herd of bison grazing on plants in grassland then the bison would be considered the trophic level directly above the grasses and other plants upon which they feed. The bison would be trophic level n and the grasses and...
