they are caused by mutation. the best example of it are human blood groups.
Rotation is the spinning of a planet, revolution is when a planet circles the sun/planet.
DNA is the molecule that carries genetic information of a given organisms. Genetic variation is the changes that occur in the genome of an organisms to help an organism adapt well to the environment, however, they might also be disadvantageous. The variation in DNA sequences are useful in building a tree of life because DNA sequences are similar in closely related organisms and less similar in less closely related organisms.

Answer:
population - community - ecosystem - biosphere
Explanation:
<em>The correctly sorted level of organization of an ecosystem from the least inclusive to the most inclusive would be from population to community to ecosystem and finally to biosphere.</em>
A population consists of a group of organism of the same species living in a particular area at a particular time and capable of interbreeding to produce fertile progeny.
A community represents different population of organisms that are interacting with one another. Several populations make up a community.
An ecosystem consists of different communities of organisms that are interacting with themselves and the non living component of the environment.
A biosphere consists of all regions of the earth where living organisms can be found. It consists of different ecosystems that make up the earth.
<u>Hence, the population is least inclusive, followed by the community, then the ecosystem and finally the biosphere.</u>
