How does the high biodiversity of the coral reef ecosystem make it more stable?

Certain species of coral will provide nutrient for others, some provide a home for other small fish, some carry plankton to feed other species of fish. I don`t know much but a great source would be coral.org.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
