Can plants use CO2 released during respiration for photosynthesis?
Question Date: 2018-04-16
Answer 1:

Yes. Plants can use any CO2 that is in the air, whether it comes from a volcano, burning plant matter, an animal respiring, another plant respiring, or even its own respired waste.

Yes - that's where the plants get the CO2 they need. They can use whatever CO2 gas they find in the atmosphere -

There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
