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? *
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.

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

Explanation:

The primary succession is a process where we have a development of an ecosystem that is changing and preparing the environment for the species of the secondary succession. The species of the first succession encounter space that doesn't have soil or any species on it, and they are the ones that manage to convert it, including the formation of the first soil. These species are not numerous, there's only small number of them, just that their populations are relatively large. When the terrain is set for the species of the secondary succession, the ecosystem already has species that occupy it, just that new ones come and create greater species diversity, thus making the ecosystem richer in species.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
