Detailed explanation-1: -Carbon dioxide is a necessary element of photosynthesis in plants. It is used in optimum amount by plants to make their food. But a high concentration of carbon dioxide can damage the plant. High concentration of carbon dioxide is not only harmful to plants but also to environment.

Detailed explanation-2: -Plants need CO2 to prepare its food by the process of photosynthesis.

Detailed explanation-3: -Plants need three main ingredients to make their food: water, carbon dioxide and sunlight. Plants take up the water that they need from the soil through their roots. Carbon dioxide is a gas found in the air; plants can take in this gas through tiny holes in their leaves.

Detailed explanation-4: -Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, an increase in CO2 concentrations in our atmosphere is causing average global temperatures to rise, disrupting other aspects of Earth’s climate.

Detailed explanation-5: -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.
