Ecological Relationships and Antlions

The video explores various ecological relationships, starting with a personal story about antlions. It explains predator-prey dynamics, using antlions and ants as examples, and discusses competition among species for resources. The video also covers symbiotic relationships, including parasitism, mutualism, and commensalism, highlighting their roles in ecosystems. Finally, it emphasizes the importance of these relationships in affecting species populations and the broader ecological impact.

What is the primary role of antlions in their ecosystem?

• Parasites

• Predators

• Decomposers

• Producers

How do antlions capture their prey?

• By building webs

• By chasing them

• By using poison

• By making sand pit traps

What happens to the antlion population if the ant population decreases significantly?

• Antlion population decreases

• Antlion population increases

• Antlion population becomes extinct

• Antlion population remains stable

What is an example of competition in ecosystems?

• Birds eating antlions

• Antlions competing for ants

• Ants building colonies

• Plants growing in the shade

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

• Water

• Light

• Soil

• Temperature

What type of symbiotic relationship involves one organism benefiting while the other is harmed?

• Parasitism

• Commensalism

• Neutralism

• Mutualism

In mutualism, how do acacia ants benefit from acacia trees?

• They gain access to sunlight

• They receive food and shelter

• They get protection from predators

• They are able to reproduce more

What is an example of commensalism?

• Lions hunting zebras

• Fleas on a dog

• Barnacles on a whale

• Ants and acacia trees

Why are ecological relationships important?

• They have no impact on ecosystems

• They are irrelevant to human activities

• They only affect individual species

• They can significantly impact populations

How can human activities affect ecological relationships?

• By stabilizing ecosystems

• By increasing biodiversity

• By threatening species populations

• By promoting mutualism
