Q: In a typical food chain, each trophic level loses 90% of the total energy it takes in from the previous level. If the producer level stores 1,000 kcal of energy, how much of this initial energy
will remain at the tertiary consumer level? A. 1 kcal B. 9 kcal C. 10 kcal D. 19 kcal
A: In a typical food chain, each trophic level loses 90% of the total energy it takes in from the previous level. If the producer level stores 1,000 kcal of energy, 10kcal of the initial energy will remain at the tertiary level. 90% of 1000 = 900; 1000 - 900 = 100 (secondary level). 90% of 100 = 90; 100 - 90 = 10 (tertiary level).
