What is the difference in place value between 2 in 324 and the 2 in 0.324

the decimal should still be there but you don’t want to have a zero so 3.42 would be correcr

Step-by-step explanation:

a is the correct

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.
