Viruses do not take in nutrients this support the classification of viruses as non-living.
What is virus?
A virus is a non-cellular, infectious entity with a microscopic structure that can live by relying on the host cell. It cannot be categorized as a living creature or a non-living material because of its parasitic nature and the traits of both living organisms and non-living substances.
The virus cannot replicate outside the host cell because it lacks the necessary cellular components. To survive, it enters the host body and attaches to a specific cell, injects genetic material, reproduces using host genetic material, and then splits the host cell, releasing new viruses.
Why viruses are considered non-living?
Viruses likewise lack the characteristics of living organisms:
- They do not have an energy metabolism, do not develop, do not generate waste, and do not respond to stimuli.
- They can't multiply on their own, thus they have to infiltrate live cells to reproduce.
Thus, we can conclude that option D is correct.
