What is primary succession quizlet?
What does primary succession end with?
On what type of land does primary succession first begin to occur?
What is primary succession?
Updated February 11, 2020. Primary succession is the type of ecological succession in which organisms colonize an essentially lifeless area. It occurs in regions where the substrate lacks soil. Examples include areas where lava recently flowed, a glacier retreated, or a sand dune formed.
What is the difference between primary and secondary succession?
Primary succession is the initial colonization of living things in a previously lifeless area. In contrast, secondary succession is the re-colonization of a region after a significant disturbance. The end result of succession is the establishment of a climax community. Primary succession requires much more time than secondary succession.
What are some examples of secondary succession?
Examples of conditions leading to secondary succession include forest fires, tsunamis, floods, logging, and agriculture.
What are the pioneer species?
Pioneer species tend to be organisms that disperse spores over great distances. Annual Herbaceous Plants: As pioneer species die, organic material accumulates and annual herbaceous plants start to move in and overtake the pioneer species. Annual herbaceous plants include ferns, grasses, and herbs.
What are some examples of terrestrial pioneer species?
Terrestrial pioneer species include lichens, moss, algae, and fungi. An example of an aquatic pioneer species is coral. Eventually, pioneer species and abiotic factors, such as wind and water, break the rock and increase the nutrient levels enough that other species can survive.
What is primary succession?
Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem ...
What are the early stages of primary succession?
The early stages of primary succession are dominated by species with small propagules (seed and spores) which can be dispersed long distances. The early colonizers—often algae, fungi, and lichens —stabilize the substrate. Nitrogen supplies are limited in new soils, ...
What are some examples of pathways?
In others, there are many possible pathways. For example, nitrogen-fixing legumes alter successional trajectories. Spores of lichen or fungus, being the pioneer species, are spread onto a land of rocks. Then, the rocks are broken down into smaller particles.
What are the causes of primary succession?
Primary succession can occur after a variety of events. These include: 1 Volcanic eruptions 2 Retreat of glaciers 3 Flooding accompanied by severe soil erosion 4 Landslides 5 Nuclear explosions 6 Oil spills 7 Abandonment of a manmade structure, such as a paved parking lot
What is the difference between primary and secondary succession?
The major difference between primary and secondary succession is the quality of the soil. Secondary succession does not require pedogenesis or soil formation. For example, primary succession would occur on barren land that was previously covered by a glacier, while secondary succession would occur on land after a forest fire.
Why are mosses important in primary succession?
Mosses are often the first organisms in Primary Succession. As these organisms die and decompose, their organic matter becomes the foundation for a thin layer of soil. Pioneer species pave the way for more complex communities of organisms because the pioneers have altered the physical environment to make it more habitable.
Why is secondary succession faster than primary succession?
Secondary succession can happen much faster than primary succession because the basis for advanced plant life is already in place. For example, after a mild forest fire, a forest can rapidly regenerate through secondary succession. Secondary succession can occur quickly after a disturbance. Secondary succession occurs after an event ...
When does secondary succession occur?
Secondary succession can occur quickly after a disturbance. Secondary succession occurs after an event that deeply disturbs an existing, stable ecosystem when most above-ground vegetation and living organisms disappear from the region.
Does secondary succession require pedogenesis?
Secondary succession does not require pedogenesis or soil formation. For example, primary succession would occur on barren land that was previously covered by a glacier, while secondary succession would occur on land after a forest fire.
What are the types of ecological succession that can lead to different compositions of species in an ecosystem over time?
It should also be noted that seasonal and cyclical succession are also types of ecological succession that can lead to different compositions of species in an ecosystem over time. These forms of succession are based on changes in available nutrients, water, and other resources over time.
When does Primary Succession Occur?
Primary Succession occurs when land becomes barren due to a major geological event or when a significant natural disaster wipes out all of the ecosystem's organisms. Once the area has been rid of its organisms, the ecosystem must start over from the Pioneer Community.
Nudation
The first step in Primary Succession is Nudation. During this step, the ecosystem is cleared by either a natural occurrence or manmade disturbance. All that is left after this event is barren rock. Examples of natural occurrence would be a volcano eruption, landslide, or glaciers melting.
Invasion
Invasion is the second step of Primary Succession. This is the phase in which organisms are successfully planted in the barren land and thriving. This occurs with simple organisms that can decompose rock.
Research Prompts
1. Primary succession generally occurs after a natural disaster, like a volcanic eruption or avalanche. Are there other types of natural disasters that can cause primary succession?
What is primary succession?
Lesson Summary. Primary succession is the initial movement of simple organisms, known as pioneer species, into new habitats that have been created. Typically, these new areas of colonization have been made available through major geological events, such as volcanic eruptions and earthquakes.
What are the organisms that are involved in primary succession?
The organisms that engage in primary succession are known as pioneer species . Typical pioneer species include simple lichens, algae, and fungi. These simple organisms begin breaking down the resources in the environment and make it suitable for the later introduction of more complex species, such as vascular plants.
What will be crowded out by the pioneer plants?
The pioneer plants will be crowded out by more complex plants, such as grasses and small shrubs that are able to live in the thin layer of newly formed soil. These small plants will continue to increase the conditions of the newly formed habitat and make way for larger species of shrubs and small- to medium-sized trees.

Primary Succession Examples
- Primary succession has been well-studied following volcanic eruptions and glacier retreat. An example is the island of Surtsey, off the coast of Iceland. An undersea eruption in 1963 formed the island. By 2008, about 30 plant species had been established. New species are moving in at the rate of two to five species per year. Forestation of volcanic land may require from 300 to 2,0…
Primary vs. Secondary Succession
- While primary succession describes the development of an ecosystem in a barren habitat, secondary succession is the recovery of an ecosystem after most of its species have been eliminated. Examples of conditions leading to secondary succession include forest fires, tsunamis, floods, logging, and agriculture. Secondary succession proceeds more rapidly than pri…

Primary Succession Overview
In primary succession pioneer species like lichen, algae and fungi as well as abiotic factors like wind and water start to "normalise" the habitat or in other words start to develop soil and other important mechanisms for greater diversity to flourish. Primary succession begins on rock formations, such as volcanoes or mountains, or in a place with no organisms or soil. Primary succession leads to conditions nearer optimum for vascular plant growth; pedogenesisor the formation of soil, and t…
