Seedless vascular plants are classified into three phyla namely the club mosses, horsetails and ferns. Ferns form the numerous seedless plants with true vascular tissue, creeping underground stems called the rhizomes and large leaves called the fronds. They reproduce via spores.
Ferns crowd on the forest floors even after cutting them down. They invade the cleared zone of forest which has been cut for timber via numerous spores. The spores are in clusters called sori on the underside of the leaves. The spores develop into haploid gametophytes by mitosis. They also grow by spreading their rhizomes or from the tips of their fronds.
Answer:
<em><u>The lack of topsoil inhibits the growth of more diverse organisms in the region.</u></em>
Explanation:
Following catastrophic or destructive events, primary succession occurs with the growth of the microorganisms. Here a non-habitable area is exploited by a colonizing organism. For instance, lichens and moss break down rock and decompose to add nutrients to sediment creating topsoil.
Ultimately, these make the environment more livable by nutrient cycling, weathering, etc., which ushers in secondary succession. Here over time, the cultures become more dynamic, more diverse and an ever-larger food web.
I think the organisms are compared to each other.
