Question

We can demarcate a facultative parasite as one which

• A. Inevitably requires living host.
• B. Only requires dead organic matter to live.
• C. Is actually a parasite but can also become saprophyte.
• D. Is actually a saprophyte but can also become a parasite.

Answer 1

The correct option is D Is actually a saprophyte but can also become a parasite.

Facultative parasites are organisms which do not completely depend on a host for completing its life cycle, but may become parasitic in absence of food or other favorable conditions

Example: Armillaria species

So, the correct answer is 'Is actually a saprophyte but can also become a parasite'
