Which statement best describes the differences in species diversity between an ecosystem beginning the process of primary succession and one beginning the process of secondary succession?
A. 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.

B. No differences in species diversity exist because both ecosystems initially lack living organisms.

C. 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.

D. Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species.
Thanks!

Answer: D. Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species.

Explanation:

Species diversity is a measure of the number and frequency of species in a community. A succession can be defined as series of changes that occur in a biotic community with respect to the changes occurring in the abiotic or non-living factors such as soil, water, availability of sunlight in a given time. A primary succession can be defined as changes that occur in an barren or unproductive land such as land undergone with volcanic eruption and regions of retreating glaciers. Such region requires long time to sustain life forms. The life forms surviving in such regions are simple.

The secondary succession occurs in regions which were previously occupied with large diversity of life forms but destroyed due to natural or human induce calamity.

Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species is the correct option because of the fact that secondary succession would be favored because the region already exhibit precursors of life like seeds and spores. These will grow and produce new life forms. The genetic variations and mutations will support the diversity of species.

Species diversity is greater in the ecosystem undergoing secondary

succession because the soil already contains seeds and spores of various

species.

What is Diversity?

Diversity is the existence of a lot of species which are present in an

ecosystem. Diversity is usually higher in ecosystem which undergo

secondary succession.

This is because the soil already contains seeds and spores of various

species. Primary succession on the other hand takes place on a bare and

barren land.
