A field of corn contains a certain amount of food energy. Compare the following situations and then answer the questions. Use th
trasher [3.6K]

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.

Savatey [412]

Label O is organic material, label A is topsoil, label B is subsoil and label C is weathered rock. They represent different soil layers.

<h3>Soil layers</h3>

Soli layers, also called horizons, refer to the different layers observed on the ground.

The topsoil is a layer of soil composed of a mixture of sand, silt, clay and organic material referred to as humus.

Weathering rocks refer to the dissolved rocks and/or minerals on the Earth's surface.
