Question

Is there a tree that gives off co2 and absorbes o2?

Answer 1

all trees (plants) do that at night, except for cam-4 plants

Answer 2

All living things respire and take in O2 and give off CO2. They do this 24/7. Green plants also do photosynthesis and make sugar and O2 . There is a dark and light reaction, but they breathe all the time.
