Detailed explanation-1: -Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Detailed explanation-2: -Carbon dioxide is essential for the plants to sustain, as it is the carbon fixed from the carbon dioxide during photosynthesis is used for synthesizing glucose. This glucose is then later used during cellular respiration to make ATP, the energy molecule.

Detailed explanation-3: -Water is necessary for photosynthesis, which is how plants use energy from the sun to create their own food. During this process, plants use carbon dioxide from the air and hydrogen from the water absorbed through their roots and release oxygen as a byproduct. This exchange occurs through pore-like stoma on the leaves.

Detailed explanation-4: -chlorophyll contained in leaf, carbon dioxide from air. water from the soil. light from the sunlight.
