Which function represents exponential decay?
f(x) = 1/5(3/2)x
f(x) = 1/5(-3/2)x
f(x) = 4(-2/3)x
f(x) = 4(2/3)x

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.
