Ecological Interactions: Exploring Mutualism Commensalism and Parasitism

The video tutorial explores various ecological interactions between species, including mutualism, commensalism, parasitism, amensalism, competition, predation, neutralism, parasitoidism, and herbivory. Each interaction is explained with examples, highlighting how species benefit, are harmed, or remain unaffected. The concept of symbiosis is also discussed, encompassing mutualistic, commensalistic, and parasitic relationships.

What type of interaction is demonstrated when both species benefit from their relationship?

• Amensalism

• Commensalism

• Mutualism

• Parasitism

Which of the following is an example of commensalism?

• Bees pollinating flowers

• Fleas on dogs

• Remoras attaching to sharks

• Lions hunting zebras

In parasitism, how is the host species affected?

• It competes for resources

• It benefits

• It is harmed

• It is unaffected

What is the term for an interaction where one species is harmed and the other is unaffected?

• Mutualism

• Commensalism

• Amensalism

• Neutralism

What happens to both species in a competitive interaction?

• Both benefit

• Both are unaffected

• One benefits, one is harmed

• Both are harmed

In predation, what is the role of the predator?

• To be consumed

• To compete for resources

• To remain unaffected

• To benefit by consuming another

Which interaction involves no effect on either species?

• Competition

• Neutralism

• Mutualism

• Parasitism

What is the outcome for the host in parasitoidism?

• The host is unaffected

• The host benefits

• The host is eventually killed

• The host competes for resources

In herbivory, what is the relationship between the herbivore and the plant?

• The herbivore benefits, the plant is harmed

• Both are unaffected

• The plant benefits

• The herbivore is harmed

Which term encompasses mutualism, commensalism, and parasitism?

• Amensalism

• Competition

• Symbiosis

• Neutralism
