Pioneer Species
A pioneer species is a species that is first to establish itself in an area where nothing is growing-or in an area that has been devastated by fire,flood, plowing etc. These species are usually annuals, disappearing after the second year when perennials take over. Pioneer species are species which colonize previously uncolonized land, usually leading to ecological succession. Pioneer species are often grasses such as marram grass, which grows on sand dunes. In more rocky and damp conditions, they are usually lichen, and small ephemeral bunchgrasses and wildflowers in crevices. The plants, or anything that has the system of a plant, to be specially to the extremes that may be experienced, and once they have modified the environment may be out-competed by less specific plants, eventually leading to a climax community.
Krindlekrax :) I used to love that book, took a while to remember it though!
The Amazon Rainforest is full of animals that all contribute to the area's ecosystem. The rainforest has primary consumers that eat the plant life. These consumers are eaten by secondary consumers, or carnivores. When the carnivores die, they are consumed by scavengers and decomposers, Then, the cycle begins again.
begins at the sun, where primary producers (plants) convert it into usable energy by photsynthesis.
No
Primary succession is when development of an area that has not had a community begins. Secondary succession is when a community starts to rebuild itself after a disturbance(Like a hurricane or tornado). Hope this helps :D
Primary Succession :)
Pioneer plants are usually present in an area where primary succession begins.
Primary succession is the process by which vegetation begins to colonize on land that has never had growth, such as a volcanic island. An example of a sentence using the term "primary succession" is "A pioneer species, such as fungi or algae, is necessary for primary succession to occur. "
It is a phenomenon or process by which an ecological community undergoes more or less orderly and predictable changes following a disturbance or the initial colonization of a new habitat. Succession may be initiated either by formation of new, unoccupied habitat, such as from a lava flow or a severe landslide, or by some form of disturbance, such as from a fire, severe wind-throw, logging, of an existing community. Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas succession that follows disruption of a pre-existing community is called secondary succession
Primary Succession- The process of succession that begins in a place previously with out plants or soil . Secondary Succession- Succession that begins in a place that already once was home of living organisms.

primary succession
Secondary succession is faster than primary succession because soil is already there and the soil usually contains many seeds.
Things in nature are not black and white, and there are intermediate stages so this makes this question somewhat difficult.Succession that begins in new habitats, uninfluenced by preexisting communities is called primary succession, whereas succession that follows disruption of a preexisting community is called secondary succession.Primary succession: the development of plant and animal life in an area without topsoil; the development of biotic communities in a previously uninhabited and barren habitat with little or no soil.Pioneer succession doesn't exist as a succession term, but pioneer species do.The definition of primary succession fits as the answer to your question.
Secondary Succession refers to the reintroduction of a community to an area that has previously supported life. Reintroduction may have to happen because a wild fire, flood or earthquake has completely destroyed life in this ecosystem. Secondary succession reaches a climax community quicker than in primary succession because spores and seeds of plants may remain in the soil. Whereas in primary succession this would all take time to come about. Just remember any type of succession starts with increasing the biomass of vegetation so that more life can be supported and more food chains evolved.
Primary succession occurs in an area with no soil or organic matter, like an area after a volcanic eruption. Secondary succession occurs where there is already soil.
Primary succession begins in areas where no soil is present.Secondary succession occurs in areas where there is soil already present.Ecological succession refers to orderly changes in an ecological community. These changes may happenbecause of the start of a new empty habitat (after a landslide, glacier, nuclear explosion, lava flow or even concreting), where all traces of previous biological material, even soil have been wiped out (Primary), orby some sort of disturbance (like bush fires, harvesting or logging) of an already existing habitat, which is not severe enough to kill everything. So plants can regrow and seeds spring up again (Secondary).Primary succession's the succession taking place at a venue where no ecosystems has ever existed (300yrs) and secondary succession's a succession at a venue where an ecosystem was once established but deceased due to human impacts or natural disasters.
