Is the process in which two groups of organisms living in the same habitat diverge into separate species. sympatric speciation adaptive radiation allopatric speciation founder event bottleneck effect gene flow

The answer could be allopatric or sympatric speciation depending on the cause of speciation. A population living in the same habitat could be separated by a physical barrier hence restricting gene flow in the population. On the other hand, sympatric speciation refers to the formation of different species from a population that is in the same habitat and geographical area without any physical separation. This could be due to differences in mating tendencies of individuals in the population  

explanation:

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.
