Symbiotic Relationships

Symbiosis is a close and long-term interaction between two different species, which can be beneficial, neutral, or harmful to one or both parties.

Commensalism is a type of symbiotic relationship where one organism benefits while the other is neither helped nor harmed.

Mutualism is a type of symbiotic relationship where both organisms benefit from the interaction.

Parasitism is a type of symbiotic relationship where one organism benefits at the expense of the other, causing harm.

Ticks feeding on the blood of mammals, benefiting the tick while harming the host.

The clownfish provides food for the sea anemone and receives protection in return.
