Answer:
The gas produced by respiration process is CO2 and it is recycled by plants during Photosynthesis.
Step-by-step explanation:
All living organisms require energy to perform their life functions. This energy is obtained by breaking down the chemical bonds in organic molecules (usually glucose). The process of respiration produces a CO2 gas and water molecule as waste products.
Naturally, plants make use of this carbondioxide (CO2) to synthesize their food (glucose). They absorb the CO2 via the stomata of their leaves. Plants fix this CO2 gas in their Chloroplast and use it produce glucose during the Calvin Cycle of Photosynthesis.
