False, it should read “Primary Consumers lose about 5% of the energy they absorb from food as heat, while Secondary Consumers lose 30% as heat.” C. False, it should read “Only Secondary Consumers lose about 30% of the energy they absorb from food as heat.” D.

The following statement is False. There is a constant flow of energy takes place from plants to plant eating animals to flash eating animals in the form of food and 90% of energy is lost as heat .

Hence, Option B is correct.

What is 10 % Law ?

Lindemann in 1942 proposed the 10% law of energy flow in ecosystem. According to 10% law if the net primary productivity is taken to be 100% in producers ( first trophic level ) then only 10% of potential energy of plant material is actually assimilated by herbivores as food  .during this act  by herbivores 90% of energy is lost as heat (thermal heat ) to the environment .

Similarly only 1% of the potential energy of primary consumers is assimilated by carnivores ( secondary consumers ) and the rest 90% of energy of carnivores  is lost as heat to the environment . Thus, during energy flow in ecosystem the energy fixed in one level is only 10% of its previous level and 90% of energy is lost as heat in each trophic level.

Thus it it concluded that there is a constant flow of energy takes place from plants to plant eating animals to flash eating animals in the form of food and 90% of energy is lost as heat .

Hence, Option B is correct.
