उत्तर
True
Explanation:
-
Plants make their food through photosynthesis, which occurs in the presence of sunlight, carbon dioxide and water.
-
During this process, plants absorb carbon dioxide and release oxygen as a by-product.
Photosynthesis equation: \[\ce{6CO2 + 6H2O ->[sunlight] C6H12O6 + 6O2}\] - So, oxygen is released during photosynthesis, which is how plants make their own food.
