They also thought that the end result of succession was a stable, unchanging final state called a climax community, largely determined by an area’s climate.
What is the stable ecosystem at the end of succession called?
A climax community refers to a stable ecosystem in its final stage of ecological succession. Succession is when one community of plants and animals replaces another in an ecosystem. In a climax community, the plants and animals are in balance with each other and their environment.
What is the most stable stage of succession?
The climax stage of ecological succession is defined by the energy balance that is achieved. This means that within this very stable ecological system, there is a balance between the life that is produced, and the life that is consumed.
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.
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.
What is the process of succession in an ecosystem?
Ecological succession is the process of change in the species structure of an ecological community over time. … It is a 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.
What is the ecological succession describe the stages of succession?
Ecological succession breaks down into three fundamental phases: primary and secondary succession, and a climax state. The study of ecological succession generally focuses on the plants present on a particular site. But animal populations also shift over time in response to the changing habitat.
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.
Why is a climax community considered the most stable?
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?
Which is a characteristic of a stable climax community? It persists until the environment changes.
What is climax persistence?
Persistence is the key to climax. In a climax community, all species (including dominant species), are continually able to reproduce successfully and persists in a uniform climatic area. That is known as climax persistance.
Which is the most stable ecosystem?
The ocean is the most stable ecosystem. It is stable due to its natural liquid nature (saline), dissolved oxygen, light and temperature.
Why are complex ecosystems more stable?
The reason greater stability is found in complex ecosystems is that with more complex interactions, the ability of organisms to deal with disturbances increases. … A food web depicts various ways in which organisms eat other organisms and obtain energy for their survival.
Which is more stable than ecological point of view?
Oceans is stable ecosystems since it stays unchanged over the long term. Various natural geological and anthropogenic forces build and damage mountains, deserts and forests but oceans have remained stable over the long history of the Earth.
