Step-by-step explanation:
First let us understand what is Photosynthesis
●Photosynthesis is the process whereby plants use carbon dioxide in the air, sunlight and water to manufacture their food and release oxygen as a by product.
Now why is the importance of photosynthesis in Nature?
● Plants have small units in their cells known as chloroplasts which contain chlorophyll to absorb sunlight. Afterwards, they use the carbon dioxide they obtain from the emission of animals and us human beings and water for the manufacturing of their food substance, glucose.
●While doing so, after making their foot substance, they release oxygen as a by product in the air, which permits us to breathe and release carbon dioxide. ( Co2)
●Photosynthesis therefore is known as a cycle to maintain the balance and composition of air in the environment constant.
if there were no Photosynthesis , there would be no oxygen in the air , that would cause a disbanlance in the atmosphere.
