species immigrating to the island and by extinction rates. It is also known as a larger island that will have a greater number of species versus a smaller island. An island is an ecosystem that is remarkably different from its surrounding area. This means an island could be a landmass surrounding by the ocean, an oasis, or surrounded by desert. Island biogeography theory also refers to the number of species on an island that helps indicates the balance between the rate at which new species become extinct. There are a couple of factors to consider regarding the rate of immigration and extinction. These factors are; isolation or distance of the island from the mainland and the size and resources on the island. The farther an island is from the mainland, there would be limited resources thus the fewer species you would be able to find. The bigger the island the more resources would be available therefore, there would be more species would be available on this habitat. Even though you could find more species on a larger island, this would create a limit on food supplies. When food supplies become scarce this would lead to natural selection, evolution, and inevitable extinction.
