Populations – Relationships in Nature
... The difference between a parasite and predator is a parasite spends most of its life in or on the host, and does not usually kill the host. The parasite has an evolutionary advantage in that it allows the host to live longer. However, the host is often weakened or exposed to disease by the parasite. ...

Human Impact
... – Predators and prey coevolve: predation is the act of one organism feeding on another. Parasitism is when one organism feeds on and usually lives on or in another organism. Parasites do not usually kill their prey (host) bc they depend on it for food and a place to live. – Plants have defenses agai ...
