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?

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

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