Solution
The correct option is A 1,00,000J
According to the 10% law of energy transmission, the energy available at any trophic level is just 10% of what it has received. The rest is either lost as heat during transfer or used up in respiration. So, the 1,000,000 J of energy will be used by the plants for their metabolism and 10% will be available at their level. So, 10% of 1,000,000 is 1,00,000 J.Hence, the correct answer is '1,00,000 J'
