Australian researchers removed a parasitic plant called mistletoe froma forest and observed the consequences. During the 3-yearexperiment, over 30% of the insect and bird species disappeared fromthe mistletoe-free forest. Another forest in which no mistletoe wasremoved saw no change in species diversity. What might the biologistsconclude from these data?

Parasitic infections

A parasite is an organism that lives in the body of another organism and obtains food at the expense of the host. There are two kinds of parasites they are internal and external. An internal parasite lives inside another organism and is known as endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite.
