Question

State the necessary condition for autotrophic nutrition and name the by-product. Mention the source of their by-product.

Answer 1

Hint: Autotrophs are organisms that can produce their food from inorganic materials. The term "autotroph" is derived from the root words "auto" for "self" and "trophy" for "food." An autotroph is a self-feeding organism that does not require the assistance of other organisms.

Complete answer:
The biochemical and physiological process by which an organism uses food to sustain its life is referred to as nutrition. Ingestion, absorption, assimilation, biosynthesis, catabolism, and excretion are all part of the process. Nutritional science is the study of the physiological processes of nutrition.

“Autotrophic nutrition is the process by which an organism prepares its food in the presence of sunlight from simple inorganic materials such as water, mineral salts, and carbon dioxide.” The term "autotrophic" is derived from the combination of two terms: "auto" (self) and "trophic" (nutrition).
Autotrophic organisms contain a green pigment called chlorophyll, which aids in the capture of solar energy. Autotrophic nutrition is found in all green plants. They produce their food through the photosynthesis process, which uses solar energy, water, and carbon dioxide. Glucose is formed as a result of this.

Photosynthesis is the process by which autotrophic nutrition occurs. Autotrophic nutrition necessitates the presence of carbon dioxide, water, chlorophyll pigment, and sunlight. Photosynthesis produces carbohydrates (food) and oxygen.

Note: The autotrophic mode of nutrition is further subdivided into two categories: photoautotrophs (uses photosynthesis as a source of energy, e.g., plants and green bacteria) and chemoautotrophs (uses chemosynthesis as a source of energy) (uses chemosynthesis, e.g., non-green sulfur bacteria).
