Changes in our surroundings that make us respond to them ,are called stimulithe process of becoming a costumes to a different environment over short period is called accumulation

Stimuli:
Stimuli can be defined as any changes or inputs that elicit a response or reaction from an organism. These changes can be internal or external and can vary in intensity and duration. Stimuli can come in various forms, such as sensory inputs, environmental changes, or chemical signals. The purpose of a stimulus is to invoke a response from an organism, which can be behavioral, physiological, or psychological in nature.

Acclimatization:
Acclimatization is a process by which an organism adjusts to the changes in its environment in order to maintain optimal functioning. It involves physiological and behavioral changes that occur over a period of time in response to a specific stimulus or set of stimuli. Acclimatization allows an organism to adapt to new or changing environmental conditions and ensures its survival and well-being.

Differences between Stimuli and Acclimatization:

Definition:
- Stimuli: It refers to any changes or inputs that elicit a response or reaction from an organism.
- Acclimatization: It is the process by which an organism adjusts to changes in its environment to maintain optimal functioning.

Nature:
- Stimuli: It can be internal or external changes that invoke a response.
- Acclimatization: It involves physiological and behavioral changes that occur in response to a specific stimulus or set of stimuli.

Response:
- Stimuli: It elicits a response from an organism, which can be behavioral, physiological, or psychological in nature.
- Acclimatization: It involves changes in the organism's physiology and behavior to adapt to the new or changing environment.

Timeframe:
- Stimuli: It can be immediate or short-term.
- Acclimatization: It occurs over a period of time as the organism adjusts to the changes in its environment.

Purpose:
- Stimuli: It serves as a trigger for a response from an organism.
- Acclimatization: It ensures the organism's survival and well-being by allowing it to adapt to new or changing environmental conditions.

Examples:
- Stimuli: Examples of stimuli include light, sound, temperature changes, touch, taste, and smell.
- Acclimatization: Examples of acclimatization include the ability of humans to adjust to high altitudes by increasing red blood cell production, or plants adapting to low light conditions by elongating their stems to reach sunlight.

In conclusion, stimuli refer to the changes or inputs that elicit a response, while acclimatization is the process by which an organism adjusts to changes in its environment. Stimuli invoke a response, while acclimatization involves physiological and behavioral changes over time to adapt to the new or changing environment.
