Question

using the 10% rule when studying trophic pyramids. if the autotrophs produce 100 joules of energy, how much energy is passed on to the herbivores? 10 joules 15 joules 0.1 joule

Explanation:

Step1: Apply 10% rule

The 10% rule states that only about 10% of the energy is passed on from one trophic - level to the next. If autotrophs produce 100 joules of energy, and we want to find the energy passed on to herbivores (the next trophic - level).
We use the formula: Energy passed on=Initial energy×10%

Step2: Calculate the energy

Energy passed on = 100×0.1 = 10 joules

Answer:

10 joules
