Here are two examples of parasites and their hosts:
Example: Flea (Parasite) and Dog (Host)
The flea is a common external parasite that feeds on the blood of its host, which can be a dog, cat, or other mammals. Fleas have specialized mouthparts that allow them to pierce the skin of their host and suck blood. They are well-adapted to cling onto the fur of the host and can reproduce rapidly, making them challenging to control.
Example: Malaria Parasite (Plasmodium species) and Human (Host)
Malaria is a deadly disease caused by the Plasmodium parasite, transmitted through the bite of infected female Anopheles mosquitoes. Once inside the human host, the parasite multiplies in the liver and then infects red blood cells, leading to recurring cycles of fever and other severe symptoms. Malaria is a significant public health concern in many tropical and subtropical regions, causing millions of cases and fatalities annually.
Both of these examples illustrate the relationship between parasites and their hosts, where the parasite benefits at the expense of the host's well-being.
I hope this helped!
