Types of Autotrophic Nutrition - About chemoautotrophs

Chemoautotrophs
Chemoautotrophs are organisms that obtain their energy from a chemical reaction (chemotrophs) but their source of carbon is the most oxidized form of carbon, carbon dioxide (CO2).
Some examples of chemoautotrophs are-
 sulfur-oxidizing bacteria, nitrogen-fixing bacteria and iron-oxidizing bacteria. Cyanobacteria are included in the nitrogen-fixing bacteria that are categorized as chemoautotrophs.

Chemoautotrophs are commonly found in environments where plants cannot survive, such as at the bottom of the ocean, or in acidic hot springs.

Types of Autotrophic Nutrition - About Photoautotrophs

Types of Autotrophic Nutrition - 1) Photoautotrophs 2) Chemoautotrophs Photoautotrophs Defination Photoautotrophs are organisms that can make their own energy using light and carbon dioxide via the process of photosynthesis The word photoautotroph is a combination of autotrop ,the word for an organism that makes its own food, and the prefix photo-, which means “light”. Green plants and photosynthetic bacteria and are examples of photoautotrophs. They are not to be confused with photoheterotrophs, which also make energy from light but cannot use carbon dioxide as their sole source of carbon, and instead use organic materials. Function of Photoautotrophs  Photoautotrophs are important because they take in carbon dioxide, a byproduct of respiration in heterotrophs. In addition, phototrophs give off oxygen as a result of photosynthesis, and animals need this oxygen in order to survive. Types of photoautotrophs- i) Green plants ii) Bacteria iii) Algea ...

Autotrophic 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 .  Types of Autotrophs Autotrophs  are capable of manufacturing their own food by photosynthesis or by chemosynthesis. Thus, they may be classified into  two  major groups: (1) photoautotrophs and ( 2 ) chemoautotrophs. By Tripti Agarwal
