Assume that 357,250,000 kilocalories are available at the producer level in this Chesapeake Bay ecosystem. Calculate the amount of usable chemical energy available at each level in the pyramid. Show your work.

357,250,000 -> 35,725,000 -> 3,572,500 -> 357,250 -> 35,725

Explanation:

only 10% of the energy at one level gets passed to the organism in the next level.

hope this helps :)

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher
