Question

If a consumer lose 70% of the 2000J energy in their food as a waste heat and 20% in their waste products. Calculate how many joules this is

Answer 1

see below for more steps

Step-by-step explanation:

If a consumer loses 70% of the 2000J energy in their food as waste heat, that would be 70/1002000 = 1400 J

And if 20% in their waste products, that would be 20/1002000 = 400 J

So the total amount of energy lost as waste heat and in waste products is 1400 J + 400 J = 1800 J
