Answer:
B
Step-by-step explanation:
Out of the options given, the factor that would have the greatest impact on the survival of a population of zebras in Africa would likely be B: climate change. Climate change can affect many aspects of an ecosystem, including changes in temperature, rainfall patterns, and vegetation growth. These changes can have ripple effects throughout the food web, impacting the availability of resources for zebras and other animals. In addition, climate change can also lead to the spread of diseases and alter migration patterns, further impacting zebra populations. While factors like tourists, flooding rivers, and dust storms can certainly have negative impacts on zebras and their habitat, they are not likely to have as significant or widespread an impact as climate change.
