Favorable morphological and physiological response to a change in environment is called

The correct answer is: D. Acclimatisation.

Acclimatisation is the physiological adjustment of an organism to a change in its environment. It is a short-term process that can be reversed if the environmental conditions change again.

Preadaptation is the possession of a trait that is not currently beneficial, but that may be beneficial in a future environment.

Ecotyping is the process by which a population of organisms becomes adapted to a particular environment.

Formation of ecophenes is the process by which the phenotype of an organism is influenced by the environment.

Here are some additional details about each of the options:

• Preadaptation: An example of preadaptation is the presence of feathers in dinosaurs. Feathers were originally used for insulation, but they later evolved to be used for flight.
• Ecotyping: An example of ecotyping is the development of different subspecies of a species in different environments. For example, there are several subspecies of the American black bear, each of which is adapted to a different habitat.
• Formation of ecophenes: An example of the formation of ecophenes is the development of thicker fur in animals that live in cold climates.
