Assume that a mature female vegetarian consumed 2 pounds of food daily for one year. At the end of this one year, she weighed ½ pound more than she weighed at the beginning of that year.

Question

a. What was the percentage of biomass conversion at this trophic level? (hint: first, think about how much total food this woman consumed in one year, and then determine what percentage of this total consumption was converted into her net weight gain for that year).
b. If she had indeed gained 10%, how much more would she weigh now?
