Which of the following examples demonstrate an ecological effect leading to an evolutionary effect?

The diversity of organisms that occurs in any particular area thus may be largely determined by the abiotic factors limiting survivorship and reproduction of organisms in a region. Which of the following limit the range of Saguaro cactus in North America? I.pollinators II.sunlight III.precipitation IV.temperature
