I want to know the answer to the following question:
How should parasite classification be viewed instead of as four isolated forms?
All the background I'm provided with is that "While a grazing species such as an elephant may travel many kilometers in a single day, grazing on many plants in the process, parasites form very close associations with their hosts, usually having only one or at most a few in their lifetime.". Is that enough to answer the question?
Answer: no
