From about 1900 to 1960, however, understanding of succession was dominated by the theories of Frederic Clements, a contemporary of Cowles, who held that seres were highly predictable and deterministic and converged on a climatically determined stable climax community regardless of starting conditions. There is no net annual accumulation of organic matter in a climax community. 1. Please respond on separate paper, following directions from your teacher.

Where explanation or discussion is required, support your answers with relevant information and/or specific examples Community A Community B (a) Identify two different scales on which biodiversity can be measured. This is different from primary succession - primary succession occurs when there is no prior vegetation on the landscape and there is no seedbank. Their quick reproduction and growth also categorizes them as R-selected species. following the establishment of pioneer species, Plant communities are established in a lifeless environment, usually devoid of soil, Aplant community becomingsimplified with fewer species and less biomass.

Earth Sciences questions and answers. However, like many of the ecosystems on Earth, the gra Because of residual fertility and pre-existing organisms, community change in early stages of secondary succession can be relatively rapid. The development of some ecosystem attributes, such as soil properties and nutrient cycles, are both influenced by community properties, and, in turn, influence further successional development. Geological and climatic catastrophes such as volcanic eruptions, earthquakes, avalanches, meteors, floods, fires, and high wind also bring allogenic changes. In lichen stage the fauna is sparse.
