|
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 that ecosystem is experiencing a longer period with a lack of competition for space.
Detailed explanation-2: -Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire.
Detailed explanation-3: -Species diversity refers to the variety of species living in a particular area. A community represents all the species in a particular ecosystem that interact with each other. On the other hand, ecosystem diversity is the variety of ecosystems in a particular area.
Detailed explanation-4: -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.
Detailed explanation-5: -Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species).
