Characteristics of Living Organisms · NCERT Biology

Why are living organisms described as 'self-regulating interactive systems'?

  1. Because they are made up of chemical compounds
  2. Because they respond to stimuli and maintain internal stability
  3. Because they steadily increase in mass over time
  4. Because they are immortal and never truly die
Show answer and explanation

Correct answer: Because they respond to stimuli and maintain internal stability

Living systems are capable of sensing changes and responding to them to maintain a steady state (homeostasis). This interaction between internal components and external stimuli defines their self-regulating nature.
