Answer: long-spined cacti will survive longer and reproduce more often than short-spined cacti
Step-by-step explanation:
The natural selection is the process of differential survival and reproduction which is facilitated by beneficial traits that some living beings posses over the others. These traits help these living beings to survive and reproduce. Thus the beneficial traits are passed on from generation to generation.
The long spines prevent the herbivorous eating better than the short spines. Thus the long spine cactus will survive and reproduce more than the short spined cactus.
