Problem:
Assume the population of the US is 320 million people, and each person requires 2000 kilocalories per day and has a 25% efficiency at using the energy in food. Based on your previous calculations, how many kg of feed would it take to provide enough food for the US if our only food source was each of the following organisms: cow, chicken, pig, and cricket?
For each organism you should provide your calculations that show how you arrived at your answer (meaning you can't just copy from one of your sources)
