Question

the 10% rule states that only 10% of the available energy is passed on to the next trophic level. if the producers have 10,000 kcal of energy available, how much is passed on to the secondary consumers? 1750 kcal 10 kcal 100 kcal

Explanation:

Step1: Determine energy passed to primary consumers

Producers have 10000 kcal. Using 10% rule, energy passed to primary consumers is $10000\times0.1 = 1000$ kcal.

Step2: Determine energy passed to secondary consumers

Using 10% rule again, energy passed from primary to secondary consumers is $1000\times0.1=100$ kcal.

Answer:

100 kcal
