90% is gained

90% is lost in light energy

|
because only 10% is lost

Detailed explanation-1: -Energy transfer between trophic levels typically follows the ten percentile rule. From each trophic level to the next, 90% of the starting energy is unavailable to the next trophic level because that energy is used for processes such as movement, growth, respiration, and reproduction.
Detailed explanation-2: -The reason for this is that only around 10 per cent of the energy is passed on to the next trophic level. The rest of the energy passes out of the food chain in a number of ways: it is released as heat energy during respiration. it is used for life processes (eg movement)
Detailed explanation-3: -Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
