Which is more, 50,000 millimeters or 5 decameters?

5 decameters.

Step-by-step explanation:

**a decimeter is 100 times bigger than a mm. a mm is 100 times smaller than a dm.**

Step-by-step explanation:

50,000 mm=5,000 cm=500 decimeter=50 m=5 decameter

so both are equal.

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.
