Karl Pfeifer

I'm not sure what you mean by "basic reasons" but the short evolutionary explanation would be that as ecosystems evolved, the biogeochemical processes in those systems evolved into cyclical processes. Since the quantities of the world's elements are limited and unchanging, evolution would favor biological processes that recycled nutrient elements.

Thanks Karl Pfeifer for his very attractive explanation in a brief and beautiful way.
