Question

differentiate between obligate parasite and facultative parasite with examples

Answer 1

Answer:

An organism that cannot survive independently of a host species. Some pathogenic organisms, including the smallpox and poliomyelitis viruses, are obligate parasites.

A facultative parasite is an organism that may resort to parasitic activity, but does not absolutely rely on any host for completion of its life cycle. Examples of facultative parasitism occur among many species of fungi, such as family members of the genus Armillaria.
