Briefly describe autotrophic mode of nutrition
Answers
Only plants are capable of combining simple inorganic substances into complex organic ones capable of sustaining life. An organism which can carry out this method of nutrition is said to be autotrophic which means self-feeding. There are two types of autotrophic nutrition, chemosynthesis and photosynthesis.
Answer:
Autotrophic nutrition is a process where an organism prepares its own food from a simple inorganic material like water, mineral salts and carbon dioxide in the presence of sunlight.”
The term “autotrophic” is formed by the combination of two terms, “auto” meaning self, and “trophic” meaning nutrition. The literal meaning of this term is self-nutrition.
The autotrophic organisms contain a green coloured pigment called chlorophyll which helps in trapping energy from the sun. All green plants possess an autotrophic mode of nutrition. They prepare their own food by utilizing solar energy, water, and carbon dioxide by the process of photosynthesis. This results in the formation of glucose.
Plants like blue-green algae and bacteria such as cyanobacteria are considered to be examples of autotrophs.
