Explanation:

Parasitism is a symbiotic relationship where one organism (the parasite) benefits at the expense of another (the host). Fleas biting humans or other animals for food is an example of this as the fleas get nourishment while the host is harmed. Weeds and wheat growing together is competition. Humming - birds feeding off flowers and moths carrying pollen are mutualistic relationships.

Fleas that bite humans or other animals for food
