Anatural disaster caused a piece of land to break away from the mainland. the landmass drifted away from the mainland and became isolated in the ocean. the landmass has a small fraction of species that were present on the mainland, and only a few individuals of each species survived. what will happen to the biodiversity of the newly formed island?
1)the biodiversity will decrease because there are fewer species on the newly formed island.
2)the biodiversity will increase because the landmass is isolated from the island.
3)there will be no change in the biodiversity of the newly formed island.
4)the species on the island will likely have lower genetic diversity than the species on the mainland.
5)the species on the island will have a higher risk of genetic mutations because they’re now on an island.
