If built, the new reservoir will flood a nearby tract of land that is the home to several native species. We Breathe Clean Air (WBCA) members oppose building the new reservoir. They think the council should focus on a campaign of water conservation first. They are preparing their own presentation to the city council. Which graph might the WBCA choose?

for b its (t) and c its (d)

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
