What is eight hundred seven thousand, eight hundred twenty five in standard form?

so you should write 8 in a box then under the box write what place it is like hundredth and you do the same for the rest

8                                       0               7           , 8              2           5

hundred thousandth^  and so on^

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.
