Consider the following statements: While eurythermal organisms are...
- Living organisms are scattered all over the world. However, their distribution is not even. Their ability to survive and reproduce is mostly dependent on abiotic factors such as temperature, pH, salinity, moisture, humidity, oxygen levels, etc. Organisms that are best adapted to the environmental conditions of that particular area are dominant while other organisms are dominant in other areas. ·
- Statement 1 is correct: Based on temperature tolerance, different groups of organisms are defined. Among them, eurythermal and stenothermal animals are two categories. Eurythermal animals are able to tolerate a wide range of temperature levels. Stenothermal animals are those which can tolerate a narrow range of temperature levels.
- Statement 2 is not correct: Eurythermal animals include cat, dog, man, goat, tiger, etc which are vertebrates (as they have a backbone and a spinal column). Thus vertebrates can be eurythermal. Although stenothermal animals include a penguin, python, crocodile, some aquatic insects survive in a narrow range of temperature, usually cool water (cold stenotherms). Insects are not vertebrates (as they lack a backbone and a spinal column). Thus all stenothermal organisms are not necessarily vertebrates.
- A few organisms can tolerate and thrive in a wide range of temperatures - eurythermal, but, a vast majority of them are restricted to a narrow range of temperatures - stenothermal.

Eurythermal and Stenothermal Organisms
The given statements discuss the concepts of eurythermal and stenothermal organisms and their temperature tolerance ranges. Let's analyze each statement separately to determine their correctness.
Statement 1: While eurythermal organisms are those organisms which can survive in a wide range of temperatures, stenothermal organisms are restricted to a narrow range of temperatures.
Eurythermal Organisms:
- Eurythermal organisms are those that can tolerate and survive in a wide range of temperatures. They have a broad temperature tolerance range.
- Examples of eurythermal organisms include certain fish, reptiles, and plants that can adapt to both cold and warm environments.
Stenothermal Organisms:
- Stenothermal organisms, on the other hand, are restricted to a narrow range of temperatures and cannot tolerate extreme temperature variations.
- These organisms are typically adapted to specific temperature ranges and cannot survive outside of their preferred range.
- Examples of stenothermal organisms include certain marine invertebrates and some species of bacteria.
Statement 2: While all vertebrates are stenothermal, all invertebrates are eurythermal.
Vertebrates and Stenothermalism:
- Vertebrates are a diverse group of animals that possess a backbone or spinal column.
- While it is not accurate to say that all vertebrates are stenothermal, some vertebrates do exhibit stenothermal characteristics.
- For example, some reptiles are stenothermal and can only survive within a narrow temperature range, while others, like birds, have higher temperature tolerances.
- However, there are also eurythermal vertebrates, such as certain fish species, that can adapt to a wide range of temperatures.
Invertebrates and Eurythermalism:
- Invertebrates are animals that do not possess a backbone or spinal column.
- It is also incorrect to state that all invertebrates are eurythermal. Invertebrates exhibit a wide range of temperature tolerances, with some being stenothermal and others being eurythermal.
- For instance, certain marine invertebrates, like corals, are stenothermal and are highly sensitive to temperature changes.
- On the other hand, some invertebrates, such as certain species of insects, worms, and mollusks, can tolerate a wide range of temperatures and are considered eurythermal.
Conclusion:
Based on the analysis, it can be concluded that Statement 1 is correct. Eurythermal organisms can survive in a wide range of temperatures, while stenothermal organisms are restricted to a narrow range of temperatures.
However, Statement 2 is incorrect. Not all vertebrates are stenothermal, and not all invertebrates are eurythermal. Both groups exhibit a range of temperature tolerances.
