Question

1. if the primary consumers receive 1,000 units of energy, how much energy do the secondary consumers get?

Explanation:

Step1: Energy transfer rule

In an energy pyramid, only about 10% of the energy is transferred from one trophic level to the next.
$$\text{Energy of secondary consumers} = 10\%\times\text{Energy of primary consumers}$$

Step2: Substitute the value

Given the energy of primary consumers is 1000 units.
$$\text{Energy of secondary consumers}=0.1\times1000 = 100$$

Answer:

100 units
