Can someone please help me with this question !

Secondary consumer level = 900 kcal of energy

Producer level = 90000 Kcal of energy

Explanation:

According to this question, there are 9000 kilocalories of energy available at the primary consumer level. Since, only about 10% of energy is transferred from one trophic level to another in a food chain, the following will be available at the secondary consumer and producer level;

Note that:

Producer → primary consumer → secondary consumer

* At the producer level; where x is the amount of energy available at the producer level.

10/100 × x = 9000kcal

10x/100 = 9000

10x = 900000

x = 900000 ÷ 10

x = 90,000 Kcal of energy.

* At the secondary consumer level:

10/100 × 9000

90000/100

= 900 Kcal of energy.
