• Parasitsm

• Commensalism

Fungi form lichens (a small plant) by living in a close relationship with algae. The fungus provides a protective home for the algae, and gathers nutrients from rainwater. The algae gathers energy from the sun using photosynthesis. Both organisms share nutrients with each other.
