Question a. Let's assume that land receives 45 joules per second per square meter (m2) of solar radiation (energy) during the spring. If there is 6.5 million ha of arable land in Bihar, India how many terajoules will reach crops over a 70 day period if there are 10 hours of sunlight per day?

Question b. If 2% of the solar energy is collected by a cereal crop like corn or wheat, how many terajoules of energy could be theoretically captured?

Question c. If 1% of solar energy captured by cereal crops is incorporated into the seeds and the average person needs 3000 MJ of energy per year, how many people can the state of Bihar theoretically feed? (Assuming here 100% of the seed mass is converted into Joules of food)

Question d. What assumptions used in the steps a through c are unlikely to be true?
