A parasite is an organism that lives on or in another, usually larger organism called a host. While the host may provide food or safety, it gets nothing in return from the parasite.
Tapeworms or ringworms are parasites sometimes found in humans.
Unlike a parasitic relationship, a symbiotic relationship is between two organisms of
different species in which one or both of the organisms may benefit or be neutrally affected.
For example, the tiny bacteria in your stomach have a symbiotic relationship with you: You
supply them with food, and they help break down your food and supply you with vitamins
that your body can't produce on its own.

In a symbiotic relationship,
?

A
one organism benefits while its host gets nothing in return.
B
bacteria takes food from your stomach, but does nothing for you.
С
both organisms involved benefit or are neutrally affected.
D
your body produces vitamins and then uses them for nutrition

A parasite is an organism, or living thing, that lives on or inside another organism. It depends on the other organism for food and other things that it needs to live. The parasite's victim is called its host. The host is usually much larger than the parasite.
