Answer:
The correct answer is - 25,00,000 Kcal
Explanation:
The transfer of energy in the trophic level is move with each successive level of the trophic level of the pyramid. Energy transfer takes place in a manner that only 10% of the available energy move to the next level and the rest 90% of energy lost as heat and other processes.
So ith producers produce 25000000 Kcal than only 10 % of this will transfer to the next level or the second level of the pyramid
Producer ----> primary consumer ----> secondary consumer
100% energy 10% energy of producer 10% of primary consumer
So, the 10% of 25000000 -----> 2500000
