Answer:
Explanation:
The upwelling of nutrients rich water to the top will increase species numbers and diversity. 
When a particular area has the ability to sustain live by providing food and nutrients required for growth of organism the population will greatly increase this is because nutrients is the major source of competition among species for survival and every species goes in search for it and where there is abundance of it there will be a rise in population and diversity. 
Varying type of species that are diverse in nature comes together, mating occurs more diverse species are formed.

there is no clear evidence about plants evolving in the desert, or fossils of any kind of cactus despite their distribution over a large area. But, scientists are of the opinion that they acquired specific attributes millions of years ago, as a response to the vastly changing climate and conditions.
-Desert plant root system
A typical desert plant has a deep root system, which is a specific physical mechanism. As the roots grow deep down the soil, they absorb soil water, which is then transported to the upper portions of the plant.
-Desert plant leaves
Bear small foliage with waxy surface to minimize transpiration (loss of water through stomatal pores), which in turn, helps to conserve water.
