Keystone species are species which has the significant and a large influence on community structure with the characteristics. It is often considerably with the lower abundance and the biomass in comparison to dominant species. If removed such species can cause a serious disruption in the structure with the function of a community.
In marine ecosystem or other type of an ecosystem in that case a keystone species defines an organism which helps to hold system together. Excluding such species, ecosystems will sound very different. Some of them might not adapt to environmental changes and if the keystone species disappeared.
