A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference. …
What is a stable ecological community that has reached equilibrium?
Climax community. a stable mature community in a successive series which has reached equilibrium after having evolved through stages and adapted to its environment.
What type of ecosystem has reached its most stable stage?
A climax community is one that has reached the stable stage. When extensive and well defined, the climax community is called a biome. Examples are tundra, grassland, desert, and the deciduous, coniferous, and tropical rain forests.
What is the stable final community of an ecosystem called?
Over time, the succession occurs in a series of plant stages, which leads to a stable final community, which is very similar to the plant community, which originally existed in the ecosystem. … This final stable plant community is called a climax community.
What are the 4 stages of ecological succession?
The complete process of a primary autotrophic ecological succession involves the following sequential steps, which follow one another:
- Nudation: …
- Invasion: …
- Competition and reaction: …
- Stabilization or climax:
Is a stable ecological community that has reached equilibrium?
An ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment. A climax community is the final stage of succession, remaining relatively unchanged until destroyed by an event such as fire or human interference.
How would you say that an ecosystem is stable?
An ecosystem is said to possess ecological stability (or equilibrium) if it is capable of returning to its equilibrium state after a perturbation (a capacity known as resilience) or does not experience unexpected large changes in its characteristics across time.
Which is the most stable climax community?
(d) Climax community. Hint: During succession over the rocks, the lichen gets replaced by forests. Similarly, in water bodies also the phytoplankton gets replaced by the forest. So, the ultimate community is the most stable community.
Why are climax communities more stable than intermediate communities?
It is the climax community that is most stable since the species that comprise it, which are the dominant late successional species, are least affected by gradual changes in the physical environment unlike the communities with lower stability.
Which is a characteristic of a stable climax community?
The final or stable community in a sere is the climax community or climatic vegetation. It is self-perpetuating and in equilibrium with the physical habitat. There is no net annual accumulation of organic matter in a climax community. The annual production and use of energy is balanced in such a community.
What is progressive succession?
progressive succession The normal sequential development of communities, from simple communities with few species and low productivity to the optimum sustainable in a given environment. It is contrasted with retrogressive successional change (retrogression).
What is the end result of ecological succession?
A climax community (Figure below) is the end result of ecological succession. The climax community is a stable balance of all organisms in an ecosystem, and will remain stable unless a disaster strikes. After the disaster, succession will start all over again.
How would you describe an ecological niche?
In ecology, the term “niche” describes the role an organism plays in a community. A species’ niche encompasses both the physical and environmental conditions it requires (like temperature or terrain) and the interactions it has with other species (like predation or competition).
What is the term that describes a steady and stable community?
What is the term that describes a steady and stable community? peak community.
What is stabilization in ecological succession?
The climax communities are best adapted to the regions of succession and the community structure is likely to continue until another disturbance steps in. This represents a steady state of ecological equilibrium with specific composition, structure and energy flow.
What are the 5 stages of ecological succession?
Stages of Ecological Succession
- Primary Succession. Primary succession occurs when organisms colonize an area devoid of life, usually after a catastrophic natural event that leaves the land barren. …
- Secondary Succession. Most ecological change occurs as secondary succession. …
- Intermediate Stages. …
- Climax Communities.
