Question

Which species can be named as dominant species?

Answer 1

Hint: The answer to this question is itself hidden in the question. The word dominant means the one having power and if needed can also influence others and create change in the ecology.

Complete step by step answer:
Ecological dominance in simple terms is defined as the degree to which a taxon is found to be more numerous than its competitors and other organisms in an ecological community, or can also be defined as the class of organisms which makes up more of the biomass. Most of the ecological communities are defined by the criteria of their dominant species.

Additional Information: Species have long been classified based on their population sizes and, as detailed above, abundant species have long been recognized as ecologically important. However, it's not clear what term is best used to describe highly abundant species, typically called common or dominant. Rabinowitz (1981) defined dominant species as people who have large local population sizes, no matter geographical range or habitat specificity. of those dominant species, Rabinowitz notes that some are common, others ‘predictable’, whereas others are ‘endemics’ (small geographical range and narrow habitat specificity). Gaston (2010) also defines common species as people who are both abundant and widespread. Such common species are also mentioned as ‘core’ species by Hanski (1982), and Mariotte (2014) suggests species whose relative abundance is > 12% should be considered dominant. These descriptions of dominant species are agnostic to the functional roles of species. Indeed, some species could also be both abundant and widespread (common), but possess traits with little impact on community or ecosystem processes, which Grime (1998) refers to as subordinate species.

Note:
Some known examples of dominant species are:
- In temperate bogs, the dominant vegetation is typically species of sphagnum.
-Tidal swamps within the tropics are usually dominated by species of mangrove (Rhizophoraceae)
-Exposed rocky shorelines are dominated by sessile organisms like barnacles and limpets.
