What are seral communities 12?
“A seral community is an intermediate stage of ecological succession advancing towards the climax community.” A seral community is replaced by the subsequent community. It consists of simple food webs and food chains. It exhibits a very low degree of diversity.
What are the types of seral community?
Depending on the substratum and climate, a seral community can be classified into water community, rock community, sand community, dry area community & saline body ommunity. This can be termed biologically as Hydrosere, Lithosere, Psammosere, Xerosere, and Halosere respectively.
What is seral stage in ecology?
Seral stage (status): a stage of secondary successional development (secondary suc- cession refers to an ecological process of progressive changes in a plant community af- ter stand-initiating disturbance).
What is seral species in biology?
Climax species, also called late seral, late-successional, K-selected or equilibrium species, are plant species that can germinate and grow with limited resources; e.g., they need heat exposure or low water availability.

Stages of Ecological Succession
- Nudation: Development of bare area or nudation without any form of life.
- Invasion: It is the successful establishment of a species in a barren area.
- Competition and coaction: After aggregation, the individuals of a species compete with other organisms for food, space and other resources.

What is meant by climax community?
[ klī′măks′ ] 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.

Secondary Succession occurs when a previously inhabited area is disturbed and then recolonised after the disruption.
