Detailed explanation-1: -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-2: -The leaves prepare food for the plants, using water and carbon dioxide in the presence of sunlight and chlorophyll. This process is called photosynthesis. The prepared food is in the form of glucose.

Detailed explanation-3: -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-4: -There are many plants that store starch in their leaves. Examples of such plants are Cabbage, Spinach, lettuce, Banana, Onion, etc.
