Solution
The correct option is D Assertion is incorrect but Reason is correct.
The living organisms are open systems because they have the ability to maintain a steady state which is considered as the process of homeostasis. They can exchange both matter and energy with their surroundings. The energy flow is a key function in the ecosystem which can be lost or gained from the external environment. This is the reason which helps to maintain the steady state in the living organisms. Thus, the correct answer is option D.
