|
|
Both photosynthesis and respiration require the same amount of energy for metabolic processes, such as synthesis and the breakdown of carbohydrates.
|
|
|
Photosynthesis releases energy for metabolism, whereas respiration requires energy for the breakdown of carbohydrates.
|
|
|
Photosynthesis requires energy for the synthesis of carbohydrates, whereas respiration releases energy during the breakdown of carbohydrates.
|
|
|
None of the above

Detailed explanation-1: -Choice (c) is correct. The products of cellular respiration are carbon dioxide and water, which are the raw materials for photosynthesis.
Detailed explanation-2: -Plants convert the light energy to chemical energy through photosynthesis. During the process, total energy is conserved.
Detailed explanation-3: -Photosynthesis absorbs energy from sunlight to build carbohydrates in the chloroplasts, and aerobic cellular respiration releases that stored energy by using oxygen to break down carbohydrates.
Detailed explanation-4: -Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. Cells then use this energy to perform work, such as cellular respiration.
