What happens when members from separated populations do not reproduce each other

2 new species evolve over time.

Say you have a group of 100 rabbits that get separated somehow and can't reproduce with each other, the rabbits on side A will become A breed or A species and the rabbits on the B side will become B breed or B species.

Sorry if that doesn't make much sense, i'm not the best at explaining things.

chlorophyll a: this is the most abundant pigment in plants. chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). it reflects green light strongly so it appears green to us.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
