Question

Bacillus ramosus and Bacillus vulgaris are examples of
A. Ammonifying bacteria
B. Nitrate bacteria
C. Nitrite bacteria
D. Symbiotic bacteria

Answer 1

Hint:These bacteria can convert ammonia to atmospheric nitrogen. Some of these bacteria can form root nodules and supply ammonia to the plants.

Complete answer:
Bacteria are small, single-celled species that live in millions, in any environment, within and outside other species. Few bacteria are toxic, but most of them have a valuable role. They serve many ways of life, both plant and animal, and are used in industrial and medicinal processes.
Ammonifying bacteria are bacteria that convert atmospheric nitrogen to ammonia. They can be either symbiotic or non-symbiotic. Symbiotic ammonia bacteria form root nodules to supply ammonia or ammonia to the plant. Non-symbiotic ammonia bacteria live easily and use ammonia for their own metabolism. Examples of ammonifying bacteria include Bacillus ramosusand Bacillus vulgaris.
Nitrifying bacteria are chemolithotrophic organisms that include representatives of the genera Nitrosomonas, Nitrobacter, Nitrococcus, and Nitrosococcus. These bacteria can absorb their energy from the oxidation of inorganic nitrogen compounds. Nitrococcus Mobilis, Nitromonouseutrophy, etc. are examples of nitrifying bacteria.
Symbiotic bacteria are bacteria that reside in symbiosis with or between other organisms. For example, Zoomastigophora, which is located in the stomach of termites, helps them to digest cellulose.

Thus, the correct answer is option A. i.e., Ammonifying bacteria.

Note:Bacteria have been among the first life forms to emerge on Earth and are found in most of its ecosystems. Bacteria occupy water, acidic hot springs, soil, nuclear waste, and the dense biosphere of the surface of the earth. Bacteria also exist in a symbiotic and parasitic relationship with animals and plants.
