Energy losses between trophic levels restrict the length of food chains and the biomass of higher trophic levels, energy losses, restrict the length of food chains, restrict length food chains, restrict biomass of higher trophic levels, biomass of trophic levels, 10%, ten percent, 10 percent, The energy added to biomass by each successive trophic level is less, energy added is less, successive trophic level, Most of the energy in food that is digested and absorbed by organisms in a trophic level is released by them in repsiration for use in cell activities, organisms absorb energy, organisms digest energy, cell respiration, use in cell activities, heat loss, lost as heat, It is therefore lost as heat, The organisms in a trophic level are not usually entirely consumed by organisms in the next trophic level, organisms not consumed, not entirely consumed, next trophic level
