Cells obtain energy by either capturing light energy through photosynthesis or by breaking down carbohydrates through cellular respiration. in both photosynthesis and cellular respiration, the energy is ultimately derived from the sun in a

The plant captures light energy and releases oxygen, which is eventually consumed in cellular respiration. Thus, the sun is the ultimate source in both the reaction. The energy is ultimately derived from the sun; this process is generally termed as a one-way process.

Further Explanation:

Photosynthesis in plants and other photosynthetic organisms is dependent on the sunlight and the other components. The plants utilize solar energy during the process of synthesizing their food along with water and other environmental factors. This energy is converted into chemical energy and stored in the plants as their biomass. Photosynthesis can be carried out by the organisms that possess the mechanism to prepare their food. This process requires trapping sunlight and using atmospheric carbon dioxide and converting them into organic nutrients.

Cellular respiration is a chemical process by which energy is produced in the form of ATP (adenosine triphosphate). They use oxygen, which is released during photosynthesis. Thus, in both reactions, the sun is the major source, though the energy resulting from the sun is a one-way process.

The correct answer is- The energy is ultimately derived from sun in a form of photons.

Explanation-

Photon is a visible light particle that is absorbed by green plants and algae in a process called photosynthesis. It is used to synthesize food that is a carbohydrate ( glucose), which is utilised for various processes.

The food synthesized through photosynthesis is consumed by heterotrophs ( like human beings) and it is used to derive energy through a process called cellular respiration ( glucose is metabolized to derive energy in the form of ATP).

Thus, in both plants and animals, the ultimate source of energy is sun.

C

Explanation:

By not having any competion in the food process, they are able to have more food.
