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: -Plants need light from the sun to complete photosynthesis and water to stay hydrated and use in creating their food. They need oxygen for respiration, and they absorb carbon dioxide from the air for the transformation into oxygen, sugar, and carbohydrates. All of these things are necessary for their survival.

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.
