when plants take in oxygen and release carbondioxide DURING THE DAY TIME IN PRESENCE OF LIGHT IT IS CALLED RESPIRATION OR PHOTO-RESPIRATION IN PLANTS.
H2O and CO2
oxygen is added to the atmosphere when plants take in carbon dioxide during cellular respiration
Carbon dioxide is the product of respiration both plants and animals.
Yes because photosynthesis occurs at a faster rate than cellular respiration
it's exactly the same as in the day; you don't need sunlight for respiration
Oxygen
Yes.
carbondioxide
co2 is exhaled during respiration & producers take it in during photosynthesis
plants during photosynthesis take in carbon dioxide and give out oxygen while animals during respiration breathe in oxygen and breathe out carbon dioxide making a complete continuous cycle.
What?? Plants don't take in oxygen. They take in carbon dioxide and make oxygen. Reread your textbook and you will be just fine.
