    I think by 'chemical energy' they mean that which is used in respiration. So the level used in respiration by produced, divided by that available at sea level, multiplied by 100 to get a percentage. Hope that helps :-)

    The only 'chemical energy' info you have is that relating to respiration. The energy released from respiration will be directly proportional to the chemical energy stored in glucose molecules. So use this knowledge to get the answer.

    Do you have the answer?

    No, actually, this is the percentage of the total light energy that was used for photosynthesis...In this case, the answer would be (6250/12.5*10^5)/100.

    OP, there is the answer....

    Ah, you are correct.

    The 10 percent rule comes to mind. Roughly 10 percent of energy from one trophic level makes it to the next.....this is a VERY rough percentage however.
