Question

name the type of energy that is used by photosynthetic organisms: chemical energy atp thermal energy sunlight

Explanation:

Photosynthetic organisms, like plants, algae, and some bacteria, perform photosynthesis. The process of photosynthesis requires light energy. Sunlight is the source of this light energy. During photosynthesis, these organisms convert light energy (from sunlight) into chemical energy (stored in glucose and other organic compounds). ATP (adenosine triphosphate) is an energy - carrying molecule produced during cellular respiration (which can occur after photosynthesis) and other metabolic processes, but it is not the initial energy source for photosynthesis. Thermal energy is heat energy and is not the energy used in the light - dependent reactions of photosynthesis. Chemical energy is the end - product (in the form of organic molecules) of photosynthesis, not the input energy.

Answer:

sunlight
