Let's say a geographical barrier separates a species into two different population. Which also cause a reproductive isolation ( the two pupolations cannot interbred)
Throughout the time (lets say a million years), the two populations will undergo a lot of changes in their respective genomes and eventually will form 2 different species.
If there is no reproductive isolation, the 2 population could interbred with one another and there will be no speciation

A community is a group of animals that coexist in the same environment
Food web is more appropriate because of how wide spread the animal kingdom is, there are many predators for many different animals. For example, if a rabbit is killed by a wolf and the wolf eats a part of the carcass and leaves it, soon other scavengers will come and eat the remains, which then spans out into a web of animals, which allows us more data than what a chain may give us to visualize.
My mom always say when in dought pick C so C
Answer:
What causes genetic variation?
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).
