Answer:

The magmatic rock or the igneous rock refers to one of the three prime kinds of rock, the others are metamorphic and sedimentary rocks. The formation of igneous rock takes place via the cooling and solidification of lava or magma.  

Of the igneous rocks, the intrusive igneous rocks form the major portion of the igneous rocks and are produced from the magma, which solidifies and cools inside the planet's crust, enclosed by pre-existing rocks. The cooling of the magma takes place gradually, and as a consequence, these rocks are coarse-grained.

Intrusive igneous rocks cool from magma slowly because they are buried beneath the surface, so they have large crystals.

Extrusive igneous rocks cool from lava rapidly because they form at the surface, so they have small crystals.

ziro4ka [17]

Denitrifying bacteria- Numerous phyla are included in the broad class of bacteria known as denitrifying bacteria. This group of bacteria, which is a part of the nitrogen cycle, may carry out denitrification together with denitrifying fungi and archaea.

Phylum (Phyla)- In biology, a phylum is a rank or level of taxonomic categorization that comes after a kingdom but before a class. Although the nomenclature for algae, fungus, and plants is recognized by the International Code of Nomenclature as being equivalent, division rather than phylum has traditionally been used in botany.
