Assertion (A): The life of living beings is dependent on a number of processes going on in their bodies like digestion, respiration, etc. All these processes are inter-related to fulfil the general needs of the body.
Reason (R): Living beings obtain the simplest forms of food after digestion and this digested food is burnt during respiration which provides energy. So, only two processes — digestion and respiration are enough for the survival of living beings.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.

Answer
A is true but R is false.
Reason — A is true as living organisms depend on many interrelated life processes such as digestion, respiration, circulation, excretion, etc. These processes work together to maintain life.
R is false as although digestion provides simpler food and respiration releases energy from it, it is incorrect to say that only digestion and respiration are enough for survival. Other processes like transport (circulation) and excretion are also essential for survival.
Therefore, A is true but R is false is the correct option.
