Question

using the 10% rule when studying trophic pyramids, if the producers produce 10,000 joules of energy, how much energy is passed on to the primary consumers? 150 joules 1000 joules 10 joule

Explanation:

Step1: Apply the 10% rule

The 10% rule states that approximately 10% of the energy is passed from one trophic level to the next.
$$Energy\ passed = 10000\times 10\%$$

Step2: Calculate the value

$$10000\times 0.1 = 1000$$

Answer:

1000 Joules
