Question

question: 12 a student is observing a single - celled alga and knows that it undergoes photosynthesis and respiration. which question could the student ask to find out how it can do both processes? a. is carbon dioxide needed for the process of photosynthesis? b. is water needed for the processes of respiration and photosynthesis? c. are the inputs of photosynthesis the same as the inputs of respiration? d. are the inputs of photosynthesis the same as the outputs of respiration?

Explanation:

To understand how a single - celled alga can perform both photosynthesis and respiration, comparing the inputs and outputs of the two processes is key. Photosynthesis uses carbon dioxide and water to produce oxygen and glucose, while respiration uses oxygen and glucose to produce carbon dioxide and water. Option D directly addresses this relationship by asking if the inputs of photosynthesis are the same as the outputs of respiration.

Answer:

D. Are the inputs of photosynthesis the same as the outputs of respiration?
