Say some example for Eurythermal and stenothermal.?

Question

Answer

Eurythermal organisms: Organisms which can tolerate and thrive in a wide range of temperature. Eg: Plants- Roses, daisies, some vegetables and fruits etc. Animals- Cat, tiger, dog etc.And Stenothermal animals are those which have the ability to tolerate only a narrow range of temperature. Examples:animal- Penguin, Python, Crocodile plants-Croton, Bougainvillea, Frangipani, vines and orchids.....

Answer

Stenothermal animals are those which have the ability to tolerate only a narrow range of temperature. Examples: Penguin.Python,Crocodile

Eurythermal animals are those which can tolerate a wide range of temperature. Examples: Cat, Dog, Tiger

Answer

Eurythermal and Stenothermal Organisms

Eurythermal and stenothermal are two terms used to describe the temperature tolerance of organisms. These terms are commonly used in the field of ecology to classify organisms based on their ability to withstand variations in temperature. Let's explore each of these terms in detail along with some examples.

Eurythermal Organisms:
Eurythermal organisms, also known as eurytherms, have a wide range of temperature tolerance. They can adapt and survive in a broad range of temperatures, both high and low. These organisms are capable of maintaining their physiological functions and metabolic activities despite fluctuations in temperature. Eurythermal organisms have a high degree of flexibility and are found in various habitats such as deserts, polar regions, and tropical rainforests.

Examples of Eurythermal Organisms:
1. Goldfish: Goldfish, a common pet fish, is a classic example of a eurythermal organism. They can tolerate a wide range of temperatures, from as low as 4°C to as high as 30°C. This adaptability allows them to survive in different aquatic environments, including ponds, lakes, and even indoor aquariums.

2. Common Dandelion: The common dandelion (Taraxacum officinale) is a flowering plant that is considered a eurythermal organism. It can withstand extreme temperature variations and is found in a wide range of habitats, from hot deserts to cold alpine regions.

3. Cockroach: Cockroaches are known for their ability to survive in various environments, including both hot and cold temperatures. They can tolerate temperatures ranging from 0°C to 50°C. This adaptability allows them to thrive in a wide range of habitats, from tropical regions to temperate zones.

Stenothermal Organisms:
Stenothermal organisms, also known as stenotherms, have a narrow range of temperature tolerance. These organisms are highly sensitive to temperature variations and can only survive within a narrow temperature range. Stenothermal organisms are typically found in stable environments with a consistent temperature.

Examples of Stenothermal Organisms:
1. Polar Bear: The polar bear (Ursus maritimus) is a stenothermal organism that is well-adapted to cold temperatures. They have a dense fur coat and a thick layer of fat, also known as blubber, which helps them withstand the extreme cold of their Arctic habitat.

2. Coral Reefs: Coral reefs are composed of stenothermal organisms, primarily coral polyps. These organisms are highly sensitive to temperature changes and can only survive within a narrow temperature range. Even a slight increase in temperature can lead to coral bleaching and eventual death of the coral reef ecosystem.

3. Alpine Plants: Alpine plants, such as the Edelweiss (Leontopodium alpinum), are stenothermal organisms that are adapted to survive in cold, high-altitude environments. They have specialized adaptations to withstand freezing temperatures, such as hairy leaves that provide insulation and protect them from desiccation.

In conclusion, eurythermal organisms have a wide range of temperature tolerance and can adapt to various temperature conditions, while stenothermal organisms have a narrow range of temperature tolerance and are highly sensitive to temperature variations. Understanding the temperature tolerance of organisms is crucial for their survival and helps us classify and study them in different ecological contexts.
