Question

What is responsiveness?

Answer 1

Hint: Changes in the environment have an effect on all organisms. Learned experience, inheritance, or adaptation can all cause these reactions. A response can take the form of an automatic, involuntary action or deliberate activity. Evolution is a sort of responsiveness that is slower but more durable. Homeostasis can be restored through physiological responses to the environment.

Complete answer :
The ability of an organism to react to changes in its internal and external settings is known as responsiveness. Moving toward sources of food and water while avoiding perceived risks is an example of responsiveness to external cues. Sweating and dilatation of blood vessels in the skin can occur in reaction to changes in an organism’s internal environment, such as increased body temperature.
An organism’s equilibrium can be restored via physiological responses to its surroundings. Mammals, for example, have innate responses to cold: they shudder and raise their fur to provide insulation. Overheated mammals react in a way that is appropriate for their body type. Humans and horses, for example, sweat. The paws of dogs sweat, but they also pant. Elephants and jackrabbits, for example, dissipate heat through their huge ears. Tigers and pigs, for example, cool themselves in water or mud.
Anatomical changes in organisms may be a response to environmental changes. Parts of the body can change. Some mammals have thick winter coats that are lost as the weather warms up in locations where temperatures vary dramatically from season to season. Hormones are the catalysts for these changes. Plants, too, respond to their surroundings by changing. Plants push their roots deeper into the ground in quest of water during a drought. This means that they will have to spend more of their energy growing.

Note :
In some cases, organisms will change their behaviour in response to their surroundings. When it comes to dealing with change, each species has its unique set of reactions. Butterflies, orcas, and ducks, for example, migrate when they notice indicators of seasonal change, such as gradual fluctuations in temperature and sunlight. Skunks and stinging insects are both attracted to and attack threats in the environment.
