Types of Ecological Relationships

The video reviews symbiotic relationships in nature, including competition, predation, mutualism, commensalism, and parasitism. It explains how these relationships can occur between animals and plants, providing examples such as squirrels competing for food, owls preying on mice, clownfish and sea anemones benefiting each other, barnacles hitching rides on whales, and ticks parasitizing dogs. The video emphasizes understanding these relationships and their ecological roles.

What is a symbiotic relationship?

Which of the following is an example of mutualism?

What is commensalism?

• A relationship where one organism benefits and the other is unaffected

• A bee collecting nectar from a flower

• A tick feeding on a dog

• A spider building a web on a gazelle's horns

• A lion hunting a zebra

What is parasitism?

• A relationship where both organisms benefit

• A relationship where one organism benefits and the other is harmed

• A relationship where both organisms are unaffected

• A relationship where one organism eats another

Which of the following is an example of parasitism?

• A clownfish living in a sea anemone

• A bee pollinating a flower

• A tick feeding on a dog

• Barnacles on a whale

In parasitism, what is the role of the host?

• The host is unaffected by the relationship

• The host benefits from the relationship

• The host competes with the parasite
