Primary succession is when there is a brand new area formed where no life has previously been. When new land is created by lava froma volcanic erruption, it is barren.

So, in your example, the order of events would be: 1, 2, 4, 3. However, the first stage in succession is generally considered when the first life takes hold, for example, when you see the first pioneer species like a lichen. Therefore, I'm not sure what the writer of the question is looking for because I don't really see a correct answer. While #1 is the first thing to occur, it's not really the beginning of succession until life shows up. #3 mentions life decomposing, but life hasn't begun yet in 1, 2, or 4.

What is the difference between primary an secondary sucession?

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


Which type of succession do the biotic components of a community cause?

The biotic components of a community can cause both primary and secondary succession. Primary succession occurs on bare rock or newly formed land, while secondary succession occurs in areas that were previously inhabited but then disturbed. Both types of succession involve the gradual replacement of species over time in response to environmental changes.


True or false an existing community is gradually replaced by another community in an ecological succession?

Ecological Succession--The gradual replacement of one community by anotherPrimary Succession--Ecological succession that happens where there are few, if any, living things.Secondary Succession--Ecological succession in a place where a community already exists.


What is succession in science?

Succession in science refers to the process by which an ecological community evolves over time. It involves a series of biological and environmental changes that occur as one community is replaced by another until a stable climax community is reached. Succession can be primary (starting from bare rock or soil) or secondary (following disturbance to an existing community).


What is ecological succesion?

Ecological succession is a fundamental phenomenon of ecology. It refers to progressive succession from unstable community to stable community. Initiation of succession is by a) formation of new inhabited area - volcanic eruption; wash out by tsunami etc. b) natural and man made calamities - fire Succession is of two types: Primary - from newly formed soil & secondary - from already existing soil. Ecological succession refers to the orderly and gradual process in a given ecosystem.

Primary succession and secondary succession?

PRIMARY SUCCESSION -SEQUENCE OF SPECIES ON NEWLY EXPOSED LANDFORMS THAT HAVE NOT PREVIOUS BEEN INFLUENCED BY A COMMUNITY e.g. AREAS EXPOSED BY GLACIAL RETREAT. SECONDARY SUCCESSION- SUCCESSION IN WHICH VEGETATION OF AN AREA HAS BEEN PARTIALLY OR COMPLETELY REMOVED BUT WHERE WELL DEVELOPED SOIL ,SEED SPORES REMAIN SO THAT THE RESULTING SEQUENCE OF SPECIES IS DRIVEN PRINCIPALLY BY INTERACTIONS SUCH AS COMPETITION AND HERBIVORE'S e.g. FAMILIAR OLD FIELDS

What is the development of a community where no life had existed before?

The answer is primary succession.


Primary succession results in a new community?

Primary succession results in a new community where no previous vegetation existed before, unlike in secondary succession which occurs where vegetation existed before and was destroyed either though human activity or naturally.


How does primary succession end?

Primary succession reaches its endpoint when a stable climax community is established. This community represents the final stage of ecological succession, characterized by a diverse and balanced ecosystem that is in equilibrium with its environment. Once the climax community is established, there is little further change in species composition.


What is the sequence of community changes that take place after a community is disrupted by natural disasters of human activities?

After a community is disrupted by natural disasters or human activities, the sequence of community changes typically involves primary succession, where pioneer species colonize the disturbed area. These species create new habitats for other organisms to establish themselves, leading to an increase in species diversity. Over time, the community reaches a more stable state through secondary succession, where more complex species interactions are established and ecosystem functions are restored.


What is the development of a stable community from new land?

Development of stable community in new land is called secondary succession .It is slower as compared to primary succession .

What would form a stable community faster primary or secondary succession?

Primary succession would form a stable community faster because it begins with bare rock or soil and the process takes longer to establish stable conditions. In contrast, secondary succession starts with existing soil and vegetation, which accelerates the recovery process and helps establish stability sooner.
