Which one of the following is most appropriately defined?A predator is an organism that captures, kills and eats another organism (its prey) for food; this definition is appropriate.
'Host' is used specifically for the organism that harbours a parasite; merely providing food does not define it (a prey or a producer also provides food).
In amensalism one species is harmed and the other is unaffected; the relationship in which one is benefited and the other unaffected is commensalism.
Parasites do not always live inside the host: ectoparasites such as lice and ticks live on the surface.
Hence the most appropriately defined term is predator.
That is every question in Organisms and Populations for this filter.
