HORTICULTURE

Detailed explanation-1: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-2: -So during the day they take in carbon dioxide and they release oxygen. And in the night, they behave almost like us. They take in oxygen and give out carbon dioxide.

Detailed explanation-3: -Interestingly, this process also uses oxygen in the same way as humans use oxygen for breathing. Fortunately, photosynthesis also uses CO2 and produces 10 times more oxygen, so plants create much more oxygen than they use. And that’s a good thing.
