Question

Compare a diet where an individual gets 500 Calories a day from rice (rice yields 1250 cal/m²/yr) with an individual who gets 500 Calories a day from beef (beef yields 130 cal/m²/yr). Calculate the number of acres needed for each diet by calculating the number of calories per year (500 x 365) and divide by the yields of each.

Answer 1

To calculate the number of acres needed for each diet, divide the number of calories per year by the yields of each. For rice, it would be 146 acres and for beef, it would be 1396 acres.

Step-by-step explanation:

To calculate the number of acres needed for each diet, we need to divide the number of calories per year (500 x 365) by the yields of each. For the diet where an individual gets 500 calories a day from rice, the yield of rice is 1250 cal/m²/yr. So, the number of acres needed would be (500 x 365) / 1250 = 146 acres. For the diet where an individual gets 500 calories a day from beef, the yield of beef is 130 cal/m²/yr. So, the number of acres needed would be (500 x 365) / 130 = 1396 acres.
