Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.

Answer:
As per my full understanding,
There are two main modes of nutrition:
Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water.
Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
WHEREBY<u>: TERMS IN THIS TWO SETS ARE:</u>
Chemohetrotroph.<em> Gets energy from chemicals and carbon from other sources.</em>
Photohetrotroph. <em>Gets energy from light and carbon from other sources.</em>
Chemoautotroph. <em>Gets energy from chemicals and produces its own carbon.</em>
Photoautotroph. <em>Gets energy from light and produces its own carbon.</em>
