When a lineage splits into multiple line of descents, then, it leads to speciation. It is a process by which a single population evolves into different species. The process of speciation leads to the development of two or more species as the lineages are splitted. These two evolved species are genetically independent.
Hence, the blank can be filled with 'speciation'.
Explanation:
yes .....................
If a bacterium uses ammonia as an energy as well as electron source, it is classified as lithotrophic chemotrophic.
<h3>Descriptive terms for lithotrophic
chemotrophic:</h3>
Humans, fungi, and also many prokaryotes are chemotrophs that get their energy from organic chemicals. Lithotrophs are chemotrophs that obtain energy from inorganic substances such as hydrogen sulfide (H2S) as well as reduced iron. Lithography is a microbiological phenomenon that is unique in the globe.
<h3>What is the difference between chemoautotrophs and chemolithotrophs?</h3>
Chemotrophs are creatures that get energy from their surroundings by oxidizing electron sources. These compounds might well be organic (chemoorganotrophs) or inorganic (chemoorganotrophs) (chemolithotrophs). The term chemotroph is used in contrast to phototroph, which uses solar energy.
