Compare and contrast primary and secondary ecological succession. How do they affect biodiversity?
primary succession occurs in previously inhabited areas, while secondary succession occurs in areas with no prior life.
primary and secondary succession are identical processes with no differences in their effects on biodiversity

Primary succession decreases biodiversity, while secondary succession always results in a return to the exact pre-disturbance ecosystem.
