Answer:

B. 720 kilocalories

Explanation:

The primary consumers use about 90% of available energy pyramid for their physical functions. In order to solve this exercise, we need to calculate the 90% of 800 kilocalories.

We can state that there is  a direct linear relationship between the kilocalories and the percentage. This means that for a higher percentage the amount of kilocalories will be greater.

We can write :

\frac{800kilocalories}{100}=\frac{x}{90}

Where the denominators are percentages.

Solving for x :

x=\frac{(800kilocalories).(90)}{100}

x=720kilocalories

The correct option is B. 720 kilocalories
