DENDROLOGY

Detailed explanation-1: -Light work Plants are called producers because they make – or produce – their own food. 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.

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: -It acts as their food and provides them energy. Plants need to synthesise their own food because unlike other living organisms, plants can not move and cannot hunt. But, for their sustenance they need food, therefore they have to make their own food.
