parasitism
association that exists between 2 organisms of different species where the parasite lives on a host and may cause harm
Parasitism is a type of symbiotic relationship that exists between two different species where one organism benefits at the expense of the other organism. The organism that benefits is called the parasite, while the organism that is harmed is called the host.
Parasites rely on the host for food, shelter, and protection, and they may live either inside or outside the host’s body. They may also cause harm or disease to the host. Examples of parasites include ticks, fleas, lice, and tapeworms.
Parasitism is often seen as a negative relationship because the host is often harmed by the parasite. However, in some cases, the relationship may be beneficial for both organisms. This type of relationship is called mutualistic parasitism, where both the host and the parasite benefit from their interaction.
Overall, parasitism is an important ecological relationship that plays a crucial role in shaping the dynamics of many different ecosystems.
