Ecological Relationships

The video explores ecological relationships, focusing on antlions as predators and their prey, ants. It discusses predator-prey dynamics, competition, and symbiotic relationships like parasitism, mutualism, and commensalism. The importance of these interactions in ecosystems is highlighted, emphasizing their impact on species populations.

What is the primary prey of antlions in their larval stage?

• Grasshoppers

• Beetles

• Ants

• Butterflies

What happens to the predator population if the prey population increases in a confined area?

• The prey population becomes extinct

• The predator population increases

• The predator population remains the same

• The predator population decreases

Which of the following is a limiting abiotic factor for plants?

• Water

• Light

• Soil

• Ants

Which of the following is an example of a mutualistic relationship?

• Antlions and ants

• Barnacles on a whale

• Fleas on a dog

• Acacia ants and acacia trees

In a commensal relationship, how is one organism affected?

• It is benefited

• It is harmed

• It is neither helped nor harmed

• It is both helped and harmed

What is a characteristic of parasitism?

• Both organisms benefit

• One organism benefits while the other is harmed

• Neither organism is affected

• Both organisms are harmed

Why are ecological relationships important?

• They have no impact on ecosystems

• They are only important for predators

• They can affect multiple species in an ecosystem

• They only affect the species directly involved
