Answer:

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

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."

Answer:

Photosynthesis has two parts: the light-dependent reactions and the dark reactions (the Calvin cycle). Photosynthesis in a general sense, uses CO2 and water to create C6H12O6 (glucose) and oxygen. The light-dependent reactions use water to make oxygen, and a reduced energy carrier (NADPH) is also created. The Calvin cycle uses carbon dioxide and ATP to create G3P for glucose.

The light-dependent reactions occur on the membrane of the thylakoid and also involve shuttling electrons across different complexes (photosystem II and photosystem I), eventually causing ATP to be created with a proton gradient.

The light-independent reactions/Calvin cycle occur in the stroma of the chloroplast and also involve shuffling carbons around. Carbon dioxide is processed in three stages, and glucose is made from 6 CO2.
