To survive the winter we will eat the bull, cow, and the wheat at the same time. A cow has 662 calories for every 453.6 grams of meat. A cow weighs 800-1000 lbs. We decided that because of the shortage of food, the cow would be 800 lbs. We converted 800 lbs into grams, which was 362,874g. Since only 41% of a cow’s total weight is consumable we multiplied .41 with the amount of grams and we got 148778.34g. We put the numbers into proportions, solved them, and got the result of 217,131 calories in a single cow. Since we have a cow and a bull it is safe to assume we will have twice as many calories to consume which will be approximately 434,264 calories. We have 500 bushels of wheat; each bushel is 60 pounds. We multiplied these numbers and got 30,000 lbs of wheat. We converted the pounds into grams and got 13,607,771g. We put the number of grams in each serving size as well as the number of calories into proportions with the total amount of grams in the wheat. By doing this, we got 46,171,800 calories of wheat. As seen in the table, the numbers used are based on these nutritional facts. We needed this information to calculate the amount of calories we will have. This will be more than enough calories for a female and male human to survive, since they both consume only 819,000 calories for a period of 9 months. Although the wheat provides enough calories for the winter, eating the bull, cow, and wheat will provide a balance in nutrition. If we risk starving the cow hoping for milk, the cow may lose body weight and provide less meat. We need calories to survive. It’s just like fuel for our bodies. In the graph, it says there are a lot of calories from fat in cows, it will provide long term energy. Fat forms long chains of molecules; this makes it able to store a lot of energy. A cow and a bull drink roughly 40-50 gallons of water a day. The 6 gallons of milk produced is not worth the loss of water. When an organism consumes another organism, it will only receive 10% of the original amount of energy. This happens after every trophic level. Relating to trophic levels, we know that if the cow and bull eats the wheat, it will only get 10% of the energy. When we eat the cow we will only get 10% of the energy as well. Therefore, we would receive more energy by eating wheat directly.
