The 10% law of energy transfer was given by _______________

Correct option is A

the 10% law of energy transfer was proposed by Lindeman in the year 1942, the transfer of energy from one trophic Level to another topic level is accompanied by loss of energy at each level, when the plants are eaten by the herbivores about 10% of energy in the food is fixed in animal flesh while 90% is consumed in ingestion, respiration, maintenance of body heat and other activities, similarly when a carnivore consumes that herbivore over again about 10% of energy is fixed therefore at each transfer only 10% of Total energy is available to the next topic level so it is called 10% law.
