What is prey? What animals would be considered prey of the two predators that you mentioned?
Parasitism is defined as a relationship between two species in which one organism (parasite) lives on or within the other organism (host), causing the host some degree of harm. A parasite reduces its host's fitness but increases its own fitness, usually by gaining food and shelter.
I am the QUEEN of this question!Answer: a parasitism is: the practice of living as a parasite in or on another organism.
Parasitism is the interaction between two species where only one benefits from the other organism and the other is harmed in return. The one that benefits from the other organism is called a parasite, while the organism that is being harmed is called a host.
