What is meant by seral stage?
In forested landscapes, the various vegetation communities that occupy disturbed sites and make up a sere are called “seral stages.” Seral-stage communities consist of vegetation types that are adapted to the site’s particular set of physical and biotic conditions.
What are the seral stages of ecological succession?
Four seral stages are recognized: potential natural community, late seral, mid seral, and early seral (Hall et al. 1995).
What are the seral stages in a community?
The individual transitional communities are termed seral stages or seral communities. In the successive seral stages there is a change in the diversity of species of organisms, increase in the number of species and organisms as well as an increase in the total biomass. Thus, the correct answer is option C.
What are the types and stages of succession?
The succession takes place due to changes in the physical environment and population of the species. The succession is mainly of two types: primary and secondary succession. The ecological succession occurs in the five stages viz nudation, invasion, competition and coaction, reaction and stabilisation.
What is the definition of primary and secondary succession?
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
What are the levels of succession?
The stages of primary succession include pioneer microorganisms, plants (lichens and mosses), grassy stage, smaller shrubs, and trees. Animals begin to return when there is food there for them to eat. When it is a fully functioning ecosystem, it has reached the climax community stage.
What are the stages of secondary succession?
The order of secondary succession is pioneer species, intermediate species, and finally climax community. The pioneer species are the first to colonize and include the producers like lichens and mosses. The intermediate species appear next and include shrubby plants and small trees.
What is serial homology in biology?
Serial homology is a method for creating new, more specialized body plans, and it is observed in species throughout the living world. see also Morphology. Carroll, Sean B., Jennifer K. Grenier, Scott D. Weatherbee. From DNA to Diversity.

What are seral stages and succession?
Seral Stages and Succession: Definition In ecological terms, a “sere” is the series of biotic communities formed by the process of ecosystem develop-ment called succession.
