Here's a breakdown:
* Parasite: The organism that benefits from the relationship.
* Host: The organism that is harmed by the relationship.
Examples of parasitism:
* Ticks on a dog: Ticks feed on the blood of dogs, causing irritation and potentially transmitting diseases.
* Tapeworms in humans: Tapeworms live inside the intestines of humans, absorbing nutrients from their host's food.
* Mistletoe on a tree: Mistletoe grows on the branches of trees, stealing nutrients and water from the host.
Key characteristics of parasitism:
* The parasite relies on the host for survival.
* The host is negatively affected by the parasite.
* The parasite often lives inside or on the host's body.
* The parasite may not always kill the host, as this would harm the parasite's own survival.
It's important to note that parasitism can be a complex relationship, with varying degrees of harm to the host. Some parasites cause minimal harm, while others can be debilitating or even fatal.
