• When two organisms live on, in or near eachother

Kinds of Symbiosis

• Commensalism • Mutualism• Parasitism

Commensalism

The sea anemone protects the clownfish and the clownfish brings food back to the sea anemone.

Parasitism

• Parasitism is when one organism receives a benefit and the other organism is harmed by the interaction.

• The one that receives the benefit is called the host and the one that is harmed is called the parasite.

Examples of Parasitism

This leech sucks blood from any animal while said animal is harmed and has some blood loss.
