Evolution occurs at the population level, not at the level of an individual organism or a species. Changes in gene frequencies within a population over time drive the process of evolution.
No. A population is every organism living in a particular area.
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.
Reproduction
An organism is an individual living thing, while a species is a group of organisms that can interbreed to produce fertile offspring. All organisms belong to a species, but a species can consist of many individual organisms.
Single individuals are naturally selected, but populations ( can be whole species ) evolve. Any mutation happening in the germ line of an individual will die with him. Only his progeny can inherit said mutation and evolve. Evolution is the change in allele frequency over time in a population of organisms.
An individual is a single organism belonging to a population, which is a group of individuals of the same species living in the same area and capable of interbreeding.
An individual organism is one single organism of a species.
No. A population is every organism living in a particular area.
Species (under the Biological Species Concept).
In "Ecology" terms, individual has pretty much the basic regular meaning we use. So Individual means, any single organism. Like the one on its own.Ecology is mostly related to study of group of organisms . If all individuals of a species in a given area are studied , it is called autecology .
A species evolves over time through the process of natural selection acting on individuals within a population. Individuals themselves do not evolve, as evolution refers to changes in the genetic composition of a population over generations.

what are examples of biotic
No. Evolution is not valid. Evolution suggests that one species changes into another species. Given all that we know about DNA, there is no possible way for any one species to change into another species even with mutations. Mutations make the individual organism weaker than the average organism of the species population and in many cases causes that organism to be sterile. Even if the individual organism does reproduce, the weak trait will be covered by the dominant allele thus rendering the mutation dormant. There would need to be a simultaneous catastrophic production of the mutation on a mass scale within the population for the mutation to even show up on a large scale in the population. Even if this magically occurred, there would not be a new species, only a new trait that shows up in the species. There is not a single documented case of any species changing into a new species.
An individual organism is one single organism of a species.
Genus and species are specific to each individual organism, so there is no genus species for all plants.
