NEET BIOLOGY

Detailed explanation-1: -Chemotrophs are organisms that obtain energy by the oxidation of reduced compounds. The substrates used by chemotrophs can be organic (organotrophs) or inorganic compounds (lithotrophs ).

Detailed explanation-2: -Chemoautotrophs are organisms that obtain energy from oxidation of inorganic substances and carbon from inorganic compounds such as carbon dioxide.

Detailed explanation-3: -Organisms such as Prokaryotes, Bacteria and Archaea, obtain the energy required for metabolism from the oxidation of reduced inorganic compounds such as hydrogen, ammonia, nitrite, sulfide, hydrogen and ferrous ions.

Detailed explanation-4: -Analogous to the harvesting of light energy by photoautotrophs, chemoautotrophs derive energy by mediating the oxidation and reduction of inorganic compounds in their environments.

Detailed explanation-5: -Chemotrophs are organisms that obtain energy by the oxidation of organic electron donors in the presence of light. Chemoautotrophs are able to synthesize their own organic molecules from the fixation of carbon dioxide. These organisms are able to produce their own source of food or energy.
