A student wants to develop an explanation of the role cellular respiration and photosynthesis play in the cycling of matter.

Answering which of the following questions would MOST help the student develop an explanation?

a
Which products of cellular respiration are also used as inputs during photosynthesis?
b
Which inputs or outputs of photosynthesis and cellular respiration are a source of heat?
c
Which type of energy is used during photosynthesis and released during cellular respiration?
d
Which cell organelles carry out the processes of photosynthesis and cellular respiration?

a) Which products of cellular respiration are also used as inputs during photosynthesis?

This question would help the student understand the connection between cellular respiration and photosynthesis and how the products of cellular respiration are used as inputs for photosynthesis. This understanding is crucial for explaining the role of these processes in the cycling of matter.
