Final answer:

The source of energy for photosynthesis is sunlight, water provides electrons for the chloroplast electron transport chain, and high-energy phosphate bonds are used to make ATP.


Explanation:

Photosynthesis: The source of energy for photosynthesis is sunlight, which is captured and converted into chemical compounds that organisms use for energy.

Water: Water is the source of electrons for the chloroplast electron transport chain in photosynthesis.

ATP: The energy used to make ATP by oxidative phosphorylation is derived from high-energy phosphate bonds.

Answer:

The correct answer is B. Sunlight.

Sunlight provides the energy for photosynthesis, which is absorbed by pigments such as chlorophyll in plants, algae, and some bacteria. This energy is then used to convert carbon dioxide and water into glucose and oxygen.

Water (A) is a reactant in photosynthesis, but not the source of energy.

Explanation:

ATP (C) is a molecule that stores energy, but it is not the source of energy for photosynthesis. Instead, ATP is produced during photosynthesis as a way to store the energy from sunlight.
