Compared to the waters of the continental shelf, the surface waters of the open ocean aregenerally much less productive in because they?,

Lack nutrients derived from the land or ocean sediment on the seabed

Natural selection has to do with variations, overpopulation, competitor and reproduction.Adaptations/variations to the environment is crucial for survival, cannot recall the question but it wasmultiple choice and the options were animals I believe .
