Understanding Parasites
Parasites are organisms that thrive at the expense of their hosts, relying on them for food and reproduction. While they can be harmful, causing weakness or even death to their hosts, not all parasites are dangerously detrimental. For instance, head lice, although annoying and itchy, are not deadly. The discussion highlights that parasites encompass a wide range of life forms, including not just animals like worms and ticks, but also plants and microorganisms such as bacteria and viruses.
