Ecological Interactions and Relationships

The video explores various interactions among living organisms, including commensalism, mutualism, parasitism, predation, and competition. Each interaction type is explained with examples, highlighting how organisms benefit or are harmed. The lesson emphasizes the importance of understanding these interactions to respect and value the natural world.

What role does the environment play in the interactions of living organisms?

• It has no effect on interactions.

• It only affects biotic factors.

• It is crucial for life processes and interactions.

• It only affects abiotic factors.

In commensalism, how is one species affected?

• One species is harmed, the other benefits.

• Both species are harmed.

• One species benefits, the other is unaffected.

• Both species benefit.

Which of the following is an example of commensalism?

• Hyenas and vultures

• Orchids and trees

• Sharks and fish

• Bees and flowers

What is mutualism?

• An interaction where one species is harmed and the other benefits.

• An interaction where both species benefit.

• An interaction where one species benefits and the other is unaffected.

• An interaction where both species are harmed.

How do bees and flowers benefit each other?

• Flowers provide nectar for bees, and bees pollinate flowers.

• Bees provide shelter for flowers.

• Bees protect flowers from predators.

• Flowers provide shade for bees.

What is parasitism?

• An interaction where both species are harmed.

• An interaction where both species benefit.

• An interaction where one species is harmed and the other benefits.

• An interaction where one species benefits and the other is unaffected.

Which of the following is an example of predation?

• Orchids growing on trees

• Bees pollinating flowers

• Birds eating worms

• Cattle egrets following cows

What is competition in ecological interactions?

• An interaction where one species benefits and the other is unaffected.

• An interaction where both species benefit.

• An interaction where both species are harmed.

• An interaction where one species is harmed and the other benefits.

What is intra-specific competition?

• Competition between plants and animals.

• Competition between members of the same species.

• Competition between predators and prey.

• Competition between different species.

Which example illustrates inter-specific competition?

• Hyenas chasing away vultures

• Bees and flowers

• Birds eating worms

• Orchids and trees
