Q. Consider the following statements:
1.Brumation is a winter dormancy state in warm-blooded mammals.
2.Estivation, or aestivation, is summer dormancy prompted by high temperatures and dry conditions.
3.Brumation is a term commonly associated with birds.
How many of the statements given above are correct?
Explanation –
Statements 1 and 3 are incorrect. Brumation is a dormancy state in cold-blooded animals, such as reptiles and amphibians, particularly in temperate regions. During brumation, these animals become inactive, and their metabolic processes slow down to conserve energy during colder months when food is scarce. Whereas, hibernation is a winter dormancy state in warm-blooded mammals. Brumation refers to the dormancy state of cold-blooded animals like reptiles and amphibians during cold weather.
Statement 2 is correct. Estivation, also known as aestivation, is a state of dormancy that some animals enter during the hot, dry summer months. This period of inactivity helps them conserve energy and water, as food and water sources may be scarce. Animals that undergo estivation include certain insects, fish, amphibians, and reptiles.
