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
