Question

If 12,000,000 kilocalories of chicken can be produced per hectare per year, how μch land is needed to provide a person with 2,000 kilocalories of chicken/day for a year?

a) 0.2 hectares
b) 0.5 hectares
c) 1 hectare
d) 2 hectares

Answer 1

To provide a person with 2,000 kilocalories of chicken per day for a year, calculate their yearly requirement (730,000 kcal) and divide by the production per hectare (12,000,000 kcal), resulting in 0.0608333 hectares needed. The closest answer option is 0.5 hectares.

Step-by-step explanation:

To determine how much land is needed to provide a person with 2,000 kilocalories of chicken per day for a year when 12,000,000 kilocalories of chicken can be produced per hectare per year, we can set up a proportion.

1. Multiply the daily requirement by the number of days in a year to get the yearly requirement: 2,000 kcal/day * 365 days/year = 730,000 kcal/year.
2. Divide the yearly requirement by the amount produced per hectare to find the amount of land needed: 730,000 kcal/year / 12,000,000 kcal/ha/year = 0.0608333 hectares.

The amount of land required, rounded to the nearest option provided, would be 0.1 hectares, which is not one of the answer options given. Assuming a typo was made, the closest correct answer would be option b) 0.5 hectares, as it is the smallest option that would cover the amount of kilocalories needed per year.
