|
Species diversity is much greater in the ecosystem undergoing primary succession because that ecosystem is experiencing a longer period with a lack of competition for space.
|
|
|
No differences in species diversity exist because both ecosystems initially lack living organisms.
|
|
|
Species diversity is much greater in the ecosystem undergoing primary succession because the lack of soil provides a greater area for organisms to claim niches.
|
|
|
Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species
|
Detailed explanation-1: -Species diversity is much greater in the ecosystem undergoing primary succession because the lack of soil provides a greater area for organisms to claim niches.
Detailed explanation-2: -Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species. Species diversity is all the differences within and between populations of species, as well as between different species.
Detailed explanation-3: -Explanation: Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity.
