Answer:
a. As the human population soars well beyond 7 billion people, so does the demand for food. That's a lot of mouths to feed! In addition to feeding humans, we also need plant-based crops to feed livestock and use for bio-energy. One of the metrics used to determine the efficiency of food production is crop yield. Simply put, crop yield is the amount of crop harvested per area of land.
