Photosynthesis in plant is chemical reaction give reason

Photosynthesis is a chemical reaction as in this the nature and identity of initial substance changes and new substance form.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Here oxygen is the by product.

Plants also respire in day time the carbon dioxide is use in the process of respiration and in night it releases in the atmosphere

Photosynthesis occurs only in day time as sunlight is needed in it

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.
