The theory was originally developed as island biogeography, to explain species richness of actual islands, principally oceanic. It proposes that the number of species found in an undisturbed insular environment is determined by immigration and extinction.
Explanation:
Wilson of Harvard, developed a theory of "island biogeography" to describe such uneven distributions. They suggested that the number of species on any island displays a balance within the rate at which new species establish it and the rate at which residents of secured species become extinct.

The answer is; Physical weathering by water would carve out the face of the cliff.
The bottom of the cliff would register the greatest weathering because of the force of the water hitting the rocks in the fall. As a cave is curved from the base of the cliff, the overhanging part of the cliff eventually collapses hence retracting the cliff a small distance upstream of the river. The diagram below demonstrates this;
The two elements that make up the most common compound in the human body are oxygen (O) at 65% and carbon (C) at 18%. I hope this helped!! Have a great day!! :)
