What are four symbiotic relationships definitions?

Answer 1

Mutualism - relationship between two organisms where both organisms benefit. Some symbiotic relationships are 'obligate', meaning that both symbionts entirely depend on each other for survival. e.g. Clownfish and Sea Anemones.

Commensalism - relationship between two organisms where one organism benefits but the other is unaffected (neither benefits nor is harmed). e.g. Barnacles and Whales.

Parasitism - relationship between two organisms where one organism benefits but the other is harmed by it. e.g. Ticks and Humans.

Amensalism - relationship between two organisms where one organism is killed by it and the other is unaffected (neither benefits nor is harmed). e.g. Allelopathy - where a plant secretes a substance which kills other plants around it, stopping competition.
