Question

The processes of photosynthesis and cellular respiration are involved in the cycling of carbon dioxide (CO₂) and

oxygen (o) among organisms.
Select at least one check box in each row to indicate the organisms that perform each process that contributes to
the carbon cycle.
Produce CO₂ that is used in photosynthesis
Use CO₂ in photosynthesis
Produce O₂ that is used in cellular respiration
Use O₂ in cellular respiration

Answer 1

Not sure but I think it’s:

1) both ; Animals and plants both respire, and CO2 is a waste product of respiration.

2) plants ; photosynthesis occurs in plants.

3) plants ; O2 is produced as a waste product of photosynthesis.

4) both ; Animals and plants use respiration to release energy and this process requires o2
