is relatively small.

The Archaebacteria is the relatively small kingdom.

Explanation:

The prokaryotes or the bacteria are single cell organisms without nucleus. The genetic material of them is present in cytoplasm and are not distinguished by any membrane organalle.

The six kingdoms of life are Archaebacteria, Eubacteria, Prostista, Fungi, Plantae, and Animalia.

Archaebacteria is the oldest organism living on the earth. They are prokaryotes , the microbes without cell nucleus and other membranes bound organelles in their cells. When the Archeabacteria are obsreved under microscope appear as bacteria. The three major groups of Archeabacteria are methanogens, halophiles and thermophiles.

Thus, Archeabacteria is considered as relatively small kingdom.

Archaebacteria is relatively a small kingdom.

Explanation:

Archaebacteria are the most established living being living on Earth. They are unicellular prokaryotes - microorganisms without cell core and some other layer bound organelles in their cells - and have a place with the realm, Archaea. Most archaebacteria seem like microorganisms, when seen under the magnifying lens.

There are three major known groups of Archaebacteria: methanogens, halophiles, and thermophiles.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
