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.

Answer 1

The energy available at the producer level in the ecosystem is 357,250,000 kilocalories. Only 10% of the energy gets transferred to the next level.

So, for first-level consumers,

=357,250,000 x 10/100

= 35,725,000 kcal of energy will be available for the first-level consumers.

For second-level consumers,

= 35,725,000 x 10/100

= 3,572,500 kcal of energy will be available for the second-level consumers.

For tertiary consumers,

=3,572,500 x 10/100

= 357,250 kcal of energy will be available for the third-level consumers.

For quaternary consumers,

= 357,250 x 10/100

= 35,725 kcal of energy will be available for the fourth-level consumers.

For this problem, use the 10% Rule. That means that every time you move up a level on the Energy Pyramid only 10% of the energy from the previous level is available at that level. Essentially, just move the decimal place over to the left one time each time you move up a level.
