Even if the theory is proven false, it is simply modified. This is why theories are much more reliable than hypotheses.
Answer: There are three energy level in the energy pyramid. The producers have the 100% energy and the primary consumers feed on the producers and obtain 10% energy the producers have and secondary consumers feed on the primary consumers.
The energy left at this level is 10% of the energy that primary consumers have.
Hence, Producers will have 475,650 kilocalories
Primary consumers will have 475,65 kilocalories
Secondary consumers will have 4756.5 kilocalories
