Question1

A is not the answer because Nitrosomonas is a genus that oxidize ammonia or nitrate as an energy source. In doing so, they convert certain fertilizers to form that is readily leached from soil, and deplete O2 in waters polluted with ammonia-containing wastes. They are comprising ellipsoidal soil bacteria. Nitrosomonas are important in the nitrogen cycle by transforming ammonium into nitrite. Which means it is an autotrophic organism that produces organic compounds from carbon dioxide as a carbon source, using either light (photoautotrophs) or reactions of inorganic chemical compound such as nitrite (chemoautotrophs), as a source of energy. An autotroph is known as a producer in a food chain. Nitrosomonas utilizes the oxidation of inorganic compounds such as nitrite as an energy source are chemoautotrophs. A lithotroph is an organism which uses an inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e. g. carbon dioxide fixation) or energy conservation via aerobic or anaerobic respiration. Nitrosomonas respire aerobically. Lithotrophs consume reduced compounds (rich in electrons). In chemolithotrophs, the compounds - the electron donors - are oxidised in the cell, and the electrons are channeled into respiratory chains, ultimately producing ATP. The electron acceptor can be oxygen (in aerobic bacteria), but a variety of other electron acceptors, organic and inorganic, are also used by various species. Photolithotrops obtain energy from light and therefore use inorganic electron donors only to fuel biosynthetic reactions (e. g. carbon dioxide fixation in lithoautotrophs).

Lithotrophs are exclusively microbes; lithotrophic pathways, all of which may use oxygen as electron acceptor:

Ð'* Nitrifying bacteria oxidize ammonia into nitrite or, alternatively, nitrite into nitrate.

Therefore Nitrosomonas is a chemolithoautotroph and not a photolithoautotroph which it does not use light/solar forces of energy. Nitrosomonas uses nitrite as an energy source. Plants and other organisms that carry out photosynthesis are phototrophs (or photoautotroph.

B is not the answer because is not the answer because Nitrosomonas is not a photoorganoheterotroph. They are from a genus that oxidize ammonia or nitrate as an energy source. In doing so, they convert certain fertilizers to form that is readily leached from soil, and deplete O2 in waters polluted with ammonia-containing wastes. They are comprising ellipsoidal soil bacteria. They are important in the nitrogen cycle by transforming ammonium into nitrite.

Nitrosomonas is an autotroph is known as a producer in a food chain. Nitrosomonas utilize the oxidation of inorganic compounds such as nitrite as an energy source are chemoautotrophs. Nitrosomonas is not a heterotrophs which are animals, fungi, as well as most bacteria and protozoaÐ'--depend on autotrophs for both energy and raw materials to make complex organic molecules. Heterotrophs obtain energy by breaking down organic molecules obtained in food, nitrite is not organic. Organotrophs are organism that obtains hydrogen or electrons from organic substrates. Nitrosomonas utilize the oxidation of inorganic compounds such as nitrite as an electron source, which makes it a lithotroph, which is an organism which uses an inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e. g. carbon dioxide fixation) or energy conservation via aerobic or anaerobic respiration. Lithotrophs consume reduced compounds (rich in electrons). In chemolithotrophs, the compounds - the electron donors - are oxidised in the cell, and the electrons are channeled into respiratory chains, ultimately producing ATP.
