Explanation:
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: -What happens to the other 90 percent of energy? It is used for metabolic processes or given off to the environment as heat. This loss of energy explains why there are rarely more than four trophic levels in a food chain or web.
