<span>An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem. For example, plants or lichens sensitive to heavy metals or acids in precipitation may be indicators of air pollution. Indicator species can also reflect a unique set of environmental qualities or characteristics found in a specific place, such as a unique microclimate. </span>

My answer:
Despite the fact that everybody realizes that seawater is pungent, not many realize that even little varieties in sea surface saltiness (i.e., convergence of broke down salts) can effectsly affect the water cycle and sea flow. Since Earth's commencement, certain cycles have served to make the sea pungent. The enduring of rocks conveys minerals, including salt, into the sea. Dissipation of sea water and arrangement of ocean ice both increment the saltiness of the sea. Anyway these "saltiness raising" factors are ceaselessly offset measures that decline saltiness, for example, the nonstop contribution of new water from streams, precipitation of downpour and day off, liquefying of ice.
I hope that helped you a lot
