Question

An animal species was found to have a wide tolerance towards salinity and habitat conditions but narrow towards temperature conditions. Which of the statements express the said species correctly
a) Stenothermal, euryhaline and euryoecious
b) Eurythermal, stenohaline and stenophagic
c) Eurythermal, euro hydric and stenoecious
d) Stenophagic , euryhaline and eurythermal

Answer 1

The organisms that have a wide range of habitats are known as euryoecious organisms. These organisms can or they have capabilities that they can stay in highly saline water or highly saline concentrations.

Complete answer:
A marine animal or an organism dwell in the soil can live at certain temperatures only are called stenothermal animals. The range of temperatures in which they can live is very low. The temperatures these organisms can handle varies from species to species. These oraganisms can't live in temperatures less than some 21°c. Examples of these organisms are reef coral, almost all the reptiles, And some insect species.
On the other hand Cryophilic animals can live only in the low temperatures sometimes they can even live at 0°c. Desert animals can't live in temperatures more than 0°. Examples of these organisms are Salman, crustaceans especially arctic crustaceans and some species of seals.
So the most important difference between these organisms is that their Survival temperatures are so different. One can handle the high temperature And one can only handle the low temperatures.
Euryhaline organisms can even live in a wide range of salinity. An example of euryhaline fish is Molly; that can live in freshwater, it can live in brackish water And it can live in saltwater. The green car was also an example of invertebrate euryhaline organisms that can live in salt as well as some other kinds of water. Diesel engines are commonly found living in the places that solitary changes quickly or regularly they usually live in tied rules.
Some of the organisms are euryhaline but they are known to migrate from saline / marine waters to the freshwaters, there in the case of salmon amd reef corals. These fishes can stay in both environments and can retain both mechanisms. We know that salmon is most famous for characteristic of being able to live in both fresh as well as salt water.That's why an organism that has a wide range of inhabitants are euryoecious organisms.

Note:- Euryhaline organisms can live in high temperatures as well as in high salinity conditions. On the other hand other organisms can live in low temperatures only. Euryhaline organisms can live in highly saline waters. Stenothermal organisms can live or survive in certain temperatures only.
