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
The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
