Diffusion occurs in all states of matter: solid, liquid, and gas. It occurs rapidly enough to be observable in a reasonable period of time, however, only in liquids and gases.
In terms of biodiversity, islands are special locations that contain a range of creatures and ecosystems for both native and endangered biodiversity. Endemism is typical of many islands. Thus islands are regarded as hot spots for biodiversity from a regional biodiversity viewpoint. In a collective portion of a basic land ecosystem it is much simpler to conserve species diversity than by shielding only one region of an archipelago.
Since every island has a specific variety of plants and animals, it is important that conservationists preserve the entire island chain. Thus allow the sources of food to differ from island to island in an archipelago. The type of producer originated in an island and then the type of consumers consuming it differ from island to island due to huge variety of and different adaptations of organisms.
