The Four Stages of Pond Succession Pondweed, and other submergent vegetation, appears and soon grow all along the bottom. Emergent plants have roots under water while part of their bodies resides above the water line. 3) Emergents then appear on the edges of the pond.

Succession is the process of ecosystem recovery after some disturbance. Biomass is at maximum in the undisturbed ecosystem; it increases up to this maximum during succession. Plant productivity also grows, especially if the plant cover was destroyed substantially by the disturbance.

Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. For example, a newly quarried rock face or sand dunes. Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.

Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.

These stages are introduction, growth, maturity, saturation, and decline.

The two major divisions of freshwater ecosystems are the lentic ecosystems and the lotic ecosystems. Lentic ecosystems are those whose water is still, and are made up of ponds, marshes, ditches, lakes and swamps. These ecosystems range in size from very small ponds or pools that may be temporary, to large lakes.

The concept of demographic transition has four stages, including the pre-industrial stage, the transition stage, the industrial stage, and the post-industrial stage.

Succession. ... In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.

There are four stages in coal formation: peat, lignite, bituminous and anthracite. The stage depends upon the conditions to which the plant remains are subjected after they were buried – the greater the pressure and heat, the higher the rank of coal.

A pond or lake ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (nonliving) physical and chemical interactions. Pond and lake ecosystems are a prime example of lentic ecosystems.

A successional stage is a change in an ecosystem that happens when one community replaces another. A climax community is a stable, mature community that results when there is little change in the composition of species.
