Detailed explanation-1: -Hence, 90% of the energy that is not transferred to the next higher trophic level is lost to the surroundings. Part C: 90% of the energy is lost to the surroundings as per the 10% rule of energy transfer. The lost energy is in form of the heat which is neither transferable nor usable.

Detailed explanation-2: -At each step up the food chain, only 10 percent of the energy is passed on to the next level, while approximately 90 percent of the energy is lost as heat.

Detailed explanation-3: -The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Detailed explanation-4: -On average, only about 10% of the energy stored as biomass in one trophic level-e.g., primary producers-gets stored as biomass in the next trophic level-e.g., primary consumers.

Detailed explanation-5: -What is the 10 percent law of energy flow? The 10 percent law of energy flow states that when the energy is passed on from one trophic level to another, only 10 percent of the energy is passed on to the next trophic level.
