Before assessing the two given cases, an assumption needs to be made about the digestion of the two types of food items, corn and beef. Let us assume that both get digested by expending same amount of energy by the human body. Let the amount of energy at producer level be an arbitrary X.
Case 1: Corn to human:
Since corn is at the producer level, it will have X amount of energy. The transfer of energy from corn to human will take place with a loss of 90% energy at the producer level. Hence the humans will receive 10% of X amount of energy.
Case 2: Corn to cow to human:
Since corn has X amount of energy, only 10% will pass to the next level, i.e. cow. So cow has 10% of X. Cow transfers only 10% of the energy that it has. Hence humans receive only 10% of 10% of X amount of energy.
It can be seen that humans receive more energy in case 1 than case 2. Hence we can say that it is more efficient for humans to feed on corn.
From the intake verses goals reports, Reuben ate 72-54 g total Fat. The DV for total fat from the nutrition facts panel (food label) is 65 g; 72.54(65 ) ×100
= 111% DV for total fat.
Too much saturated fat may raise the amount of cholesterol in blood, which can increase the risk of heart disease, thus one should consume no more than the recommended daily intake.
Because with out energy we wouldn't be moving and we would always be sleeping.
