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? 10 joule 1000 joules 150 joules

Explanation:

Step1: Identify the energy - transfer rule

The 10% rule means 10% of energy is passed from one trophic level to the next.

Step2: Calculate the energy passed to primary consumers

The energy of producers is 10000 Joules. The energy passed to primary consumers is 10% of 10000 Joules, which is $10000\times0.1$.
$10000\times0.1 = 1000$ Joules

Answer:

1000 Joules
