Question

Assume there are 1000 units of energy in the producer level of the energy pyramid. How many units of energy are available at each of the three consumer levels? Show your calculations.

Answer 1

Answer:

Energy retained at consumer level 1 - $100$ units

Energy retained at consumer level 2 - $10$ units

Energy retained at consumer level 3 - $1$ units

Explanation:

The total units of energy $= 1000$ lies at the producer level of the energy pyramid.

Now at each trophic level only 10% of the energy of its previous level is passed on which means at

Consumer level 1 -

energy retained $= 10$ % energy at producer level

$= \frac{10}{100} *1000\\= 100$ units

Like wise -

Energy retained at consumer level 2 -

$\frac{10}{100} * 100\\= 10$ units

Energy retained at consumer level 3 -

$\frac{10}{100} * 10\\= 1$ units

Thus,

Energy retained at consumer level 1 - $100$ units

Energy retained at consumer level 2 - $10$ units

Energy retained at consumer level 3 - $1$ units
