John grows corn and oranges. The oranges are grown in a large greenhouse. This takes a great deal of effort and money. The corn is much easier to grow because it grows naturally in his climate. Which crop does he have the comparative advantage? Explain why.

A comparative advantage is the ability to complete an activity more efficiently than another economic activity. The crop that John grows that has the comparative advantage is corn. This is due to it's ability to grow naturally in the climate that he lives in. John's oranges have to be grown in a greenhouse which is costly and takes a lot of effort, which makes them not as efficient to grow than his corn.
