Trivia: What is NOT a type of symbiosis?
Predation
Commensalism
Mutualism
Parasitism
Correct Answer: Predation
So why is this answer correct? : The four types of symbiosis in biology are mutualism, commensalism, parasitism, and competition. Mutualism is a relationship that benefits both parties, like clownfish and sea anemones. Commensalism benefits one party and doesn’t impact the other, like a bird building a nest in a tree. Parasitism typically hurts one party, such as a mosquito biting a human. Finally, competition is when species compete for the same resources in one ecosystem, like sea sponges and coral or bears and wolves.
