What kind of response does 'stress' pertain to in an organism?

The concept of 'stress' in an organism primarily pertains to responses that exceed its ability to cope. When an organism encounters a demand or challenge that overwhelms its capacity to manage, it experiences stress. This can manifest through various psychological and physiological responses, indicating that the organism is struggling to adapt to the perceived threat or adversity.

It is important to recognize that stress isn't solely about negative experiences; it encompasses a range of responses that can be both internal and external. The body may react with increased heart rate, heightened alertness, or other physiological changes to manage the perceived threats, highlighting the intricate connection between stress and an organism's coping mechanisms. Thus, the correct understanding of stress focuses on the threshold of coping and the extensive range of responses an organism may exhibit when facing challenges.
