Question

If the total amount of energy in the producer level of an ecosystem is 40,000 kilocalories, approximately how much energy is available for the primary consumers?

Answer 1

Hey there!

Answer: 400 k-cal

I remember learning that 4,000 k-cal would be approximately 40 k-cal for the primary consumers, which, that would be how much would be available. Now, if we would want for the primary consumers to consume more k-cal, it's obvious that there would then have to be more k-cal from the producers level of the ecosystem.

Formula of k-calories: k-cal÷20(4)= k-cal = k-cal × 2 = k-cal

As we plug in this formula into our problem above, our answer would be explained below.

40,000 ÷ 20 = 2,000 × 2 = 4,000 ÷ 100 = 400 k-cal

Answer: 400 k-cal

Answer 2

the answer is 4000 i got it right on my test.
