10927.	Question : Organisms at a higher trophic level have less energy available. Comment
Answer» Solution :As per Lindman 10 per CENT less energy is transferred to in FLOW of energy in ecosystem. As per this law `10%` of energy is obtained at each trophic level and energy gets converted at other level. As we go higher to the trophic level, the energy obtained to living organisms get decreased. Thus high camivores get the LEAST energy in food chain heat energy in food chain heat energy becomes less. Thus heat energy remains till respiration. `10%` ehergy flow low showing transfer of energy from one trophie level to OTHERS
