Parasitism is a type of biological relationship where one organism benefits while the other is harmed.
Parasitism
🧠 Simple meaning
A parasite lives on or inside another organism (the host) and takes nutrients or resources from it, usually causing harm.
🧫 Key parts
- Parasite → benefits (gets food or shelter)
- Host → is harmed
🐛 Examples
- Ticks on dogs (tick feeds on blood, dog is harmed)
- Tapeworm in humans (absorbs nutrients from intestines)
- Mosquitoes biting humans (female mosquitoes feed on blood)
- Mistletoe on trees (takes water and nutrients)
🌿 Types of parasites
- Ectoparasites: live on the outside (lice, ticks)
- Endoparasites: live inside the body (worms, protozoa)
⚖️ Important idea
Parasitism is different from:
- Mutualism (both benefit)
- Commensalism (one benefits, other unaffected)
🧠 In one line
Parasitism = “one wins, one suffers” relationship in nature.
If you want, I can also compare parasitism with mutualism in a simple table.
