Question

Define about(a) euryhaline and stenohaline, (b) Euraithermal and stenothermal​

Answer 1

Answer + Explanation:

a)

Euryhaline organisms are able to adapt to a wide range of salinities. An  example of a euryhaline fish is the molly (Poecilia sphenops) which can live in fresh water, brackish water, or salt water. ... The opposite of euryhaline organisms are stenohaline ones, which can only survive within a narrow range of salinities.

b)

Eurythermal animals and stenothermal animals are two groups categorized based on the range of temperature tolerance. Eurythermal animals are those who can survive at a wide range of temperatures. They show reduced temperature sensitivity. Stenothermal animals are those who can survive at a narrow range of temperatures.

Answer 2

Ans=Stenothermal animals: a marine or soil-dwelling animal that is capable of living only at a certain temperature or within a very narrow range of temperatures. The temperature to which stenothermal animals are adapted varies from species to species. Thermophilic animals can live only at relatively high temperatures, usually no lower than 20C (for example, reef corals, some insect species, and most reptiles). Cryophilic animals can live only at low temperatures, sometimes as low as 0C (for example, some species of seals, arctic crustaceans, and salmon). Stenothermal animals contrast with eurythermal animals, which can tolerate a wide range of temperatures.
