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 10 joule 1000 joules

Explanation:

Step1: Apply the 10% rule

The 10% rule states that approximately 10% of the energy from one trophic level is passed on to the next. If producers (first trophic level) have 10,000 Joules of energy, and primary consumers (second trophic level) get energy from producers.
We calculate the energy passed on as \(10000\times 10\%=10000\times\frac{10}{100}\)

Step2: Perform the calculation

\(10000\times\frac{10}{100}=\frac{10000\times10}{100}= 1000\) Joules

Answer:

1000 Joules
