Question

Plants manufacture their food by using………. energy.

Answer 1

Hint: Plants are photosynthetic eukaryotic organisms which include all living things that are not animals and all algae and fungi that are treated as plants. By the process of photosynthesis plants get energy through the sunlight that also contain chlorophyll A and B giving them their characteristic green color.

Complete answer:
Plants manufacture their food by using solar energy. Chlorophyll absorbs the sunlight and gives green color to the plant. This solar energy is converted into chemical energy which is stored in the form of food. Carbon dioxide and water are the raw materials that are used during the process of photosynthesis and are converted into glucose with the release of oxygen. Plants can make their food. They are known as autotrophs. Those organisms that use carbon from simple substances like carbon dioxide to produce organic compounds and use energy from sunlight. They do not need a living source and are the producers in a food chain like that of algae in water and plants on land. They help in reducing carbon dioxide to make organic compounds for the biosynthesis of organic compounds and stored them as chemical fuels.

Additional information:
Plants make their food by the process of photosynthesis in the presence of sunlight. They convert electromagnetic energy from sunlight into chemical energy in the form of glucose including methanogens which are chemotrophs that use organic or inorganic chemical compounds as their source of energy. The plant consumes the dead and decaying matter from the soil for their nutrients and gets consumed by the plant-eating animals for their survival. The end products of photosynthesis are oxygen which is released by the plants and carbohydrates that become the plant's source of energy.

Note: Green plants have chlorophyll (green coloured pigments) present on the surface of green coloured parts of the plants, these chlorophyll helps in synthesis of food(glucose) in plants. This process is known as photosynthesis. The process occurs only when sunlight, water, carbon dioxide and chlorophyll are present. Thus Green plants are known as Photoautotrophs. As Green plants synthesise their own food (autotrophs) in the presence of sunlight (light means photo).
