Answer:
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.
