Ecological Relationships and Interactions

The video explores various relationships in ecosystems, focusing on interactions like predator-prey dynamics, competition for resources, and symbiotic relationships such as mutualism, commensalism, and parasitism. Examples include herbivores, carnivores, and omnivores, as well as specific cases like honeybees and flowers, zebras and egrets, and parasitic birds. The video highlights how these interactions shape ecosystems.

What is the primary interaction in a predator-prey relationship?

• Animals live in harmony

• Animals compete for resources

• Animals share resources

• One animal eats another

Which type of organism eats both plants and animals?

• Detritivore

• Omnivore

• Herbivore

• Carnivore

What is an example of competition in an ecosystem?

• Two animals fighting over territory

• A bird building a nest

• A lion hunting a zebra

• A bee pollinating a flower

In mutualism, how do both organisms benefit?

• One organism is harmed

• Both organisms are unaffected

• Both organisms benefit

• One organism benefits, the other is unaffected

Which of the following is an example of mutualism?

• A mosquito feeding on blood

• A bee pollinating a flower

• A bird nesting in a tree

• A lion hunting a gazelle

What is the relationship called when one organism benefits and the other is unaffected?

• Parasitism

• Commensalism

• Mutualism

• Predation

Which of the following is an example of commensalism?

• A lion hunting a gazelle

• An egret following a zebra

• A bee pollinating a flower

• A mosquito feeding on a human

In parasitism, what happens to the host organism?

• It is harmed

• It is unaffected

• It benefits and is harmed

• It benefits

Which of the following is an example of parasitism?

• A bee pollinating a flower

• A mosquito feeding on blood

• An egret following a zebra

• A lion hunting a gazelle

What is a common outcome for the host in a parasitic relationship?

• The host benefits

• The host is unaffected

• The host is harmed

• The host and parasite both benefit
