A graphic organizer is also known as a knowledge map, a concept map, a story map, an advance organizer and cognitive organizer. It is a pedagogical tool that makes use of visual symbols to express knowledge and concept through relationship between them.
In the graphic organizer shown in the question, the graphic organizer of option A best compares natural selection (which are driven by the environmental factors) and the artificial selection (which are driven by the human factors).
Artificial selection is a human-induced process, that is, it does not occur naturally. In this process, the human being conducts successive crossings between two living beings in order to establish certain characteristics desired in the offspring resulting from these crossings.
Natural selection, on the other hand, is the process that governs the natural selection of species. This process states that only species adapted to the environment in which they live will have the ability to survive and the characteristics that allowed this adaptation will be transmitted to the descendants of that species.
Both natural selection and artificial selection are based on hereditary variation.
