Question

Which of the following best describes how the

chemical energy travels up the food pyramid?
A. Chemical energy is used by each of the
organisms in the food pyramid, resulting in less
energy as it moves up the pyramid.
B. Chemical energy is made by each of the
organisms in the food pyramid, resulting in more
energy as it moves up the pyramid.
C. Chemical energy is not needed by the
organisms in the food pyramid, resulting in equal
amounts of energy throughout the food pyramid.
D. Chemical energy is used by producers but
created by consumers, resulting in fluctuations
in the amounts of energy throughout the food
pyramid

Answer 1

A. Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid.

Step-by-step explanation:

Answer 2

A. Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid.

Step-by-step explanation:

Green plants are autotrophs. They manufacture their own food through photosynthesis. Through sunlight, the food manufactured has chemical energy stored in them which is made available to the heterotrophs. Heterotrophs are mainly consumers, while autotrophs are producers.

Heterotrophs rely on autotrophs for their nutrition.

Thus, as consumers above at the top of the pyramid feeds on those below, the stored energy is being transferred up and used. These energy reduces as it goes up right to the top of the pyramid.

The best statement that describes how chemical energy is transferred up the pyramid is: "A. Chemical energy is used by each of the organisms in the food pyramid, resulting in less energy as it moves up the pyramid."
