What are the four stages of succession?
The complete process of a primary autotrophic ecological succession involves the following sequential steps, which follow one another:
- Competition and reaction:
- Stabilization or climax:
What is intermediate stage of succession?
A seral community is an intermediate stage found in ecological succession in an ecosystem advancing towards its climax community. In many cases more than one seral stage evolves until climax conditions are attained.
What is the correct sequence of given steps of succession?
Trees → Shrubs → Lichens → Mosses → Grasses.
What is the first stage of succession?
The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens. Lichens begin breaking down a rock. Seasonal cycles of freezing and thawing form cracks in the rock.
What is the second stage of succession on bare rock?
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.
What are the stages of secondary succession?
Stages of Secondary Succession
- Growth exists.
- Existing growth is destroyed.
- Destruction stops.
- The soil remains.
- Time goes by.
- Regrowth begins.
- Fast-growing plants and/or trees are dominant for a while.
- Slower growing plants and/or trees come back and begin growing.
What is the latest stage of succession?
Climax – the climax stage is the last stage of an ecosystem. It is when the ecosystem has become balanced and there is little risk of an interfering event or change to mutate the environment.
