what is Autotrophic nutrition? Explain in brief with example.
Answers
Answer:
The mode of nutrition in which organisms make their own food using sunlight, water, and carbon dioxide is known as autotrophic mode of nutrition . For eg- Green plants. ... They prepare their own food by utilizing the trapped solar energy, water, and carbon dioxide by the process of photosynthesis.

Answer:
Auto = self, Trophic = nutrition. The exact meaning of this word is self-nutrition. Autotrophic nutrition is a process in which the organism produces their food from the simple inorganic materials such as water, carbon dioxide and mineral salts in the presence of sunlight. All the green plants have an autotrophic mode of nutrition.
The autotrophic organisms have a green colored pigment named “chlorophyll” which helps in catching energy from the sun. They make their own food with the help of the water, solar energy, and carbon dioxide by the method of photosynthesis. This results in the making of glucose.
Plants such as blue-green algae and cyanobacteria could be considered as some examples of autotrophic nutrition.
Nutrition in Plants
Every living organism wants some kind of energy and nutrient substances to ensure that the life processes run smoothly. Besides, this energy needed is acquired from the food.
Plants and Their Nutrition Requirements
Plants are also a part of living things that require some form of energy. They have cells and tissues. They also grow in girth and size. And they are the creators of the ecosystem. So, in order to create food, they do have nutrient necessities. Of course, the kind of nutrient requirements differs.
This type of nutrition in plants is so-called the “autotrophic mode of nutrition”. What does this actually stand for? It means that plants have the special ability to make their own food, with the help of simple inorganic substances to harvest organic substances. They get energy sources from non-living things like sun and carbon dioxide CO2.
Plants also contain chlorophyll in them, the green color pigment. With the help of all these above elements, plants can yield simple carbohydrates. The carbohydrates thus made are utilized by the plant and gives it energy. When there is a surplus of carbohydrates in the plants, then it is stored as a backup for later use.
