In a study of energy flow, the following data were collected:

Each human requires 55 grams of protein per day.
An acre of soybeans produces 200,000 grams of protein per year.
A cow grazing on one acre of land produces 19,000 grams of protein per year.

Based on these data, an acre of land would support:

10 humans per year on a diet of soy, or 0.9 human per year on a diet of beef.

What is the statements that best explains these relationships in terms of energy transfer?

Answer:

The requirement of proteins by 10 persons during a year is:  

     55 x 10 x 365 = 200,750 grams of proteins

Explanation:

The statement that explains these relationships in terms of energy transfer is the fact that cows produce less mass (and therefore less proteins) because they need to eat and energy is lost as entropy during this process
