Detailed explanation-1: -Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means ‘making out of light’. The foods are called glucose and starch.
Detailed explanation-2: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.
Detailed explanation-3: -Plants use their leaves to make food. The plant’s leaves act like solar panels, soaking up the Sun’s energy. The leaves contain a green pigment (colored chemical) called chlorophyll, which is essential in this process.
