Ecological Interactions and Relationships

The video tutorial, presented by Lucilian Paranyo Dana, covers the major interactions among species within an ecological community. It explains six types of interactions: competition, predation, herbivory, mutualism, parasitism, and commensalism. Each interaction is defined and illustrated with examples, highlighting how species interact for resources, survival, and mutual benefits. The video aims to educate viewers on these ecological concepts using a PowerPoint presentation with digital art, emphasizing its educational purpose.

What is the primary focus of the introduction section in the video?

• An overview of the six major interactions among species

• The importance of biodiversity

• The role of humans in ecosystems

• The definition of ecological communities

Which of the following best describes competition among species?

• A predator-prey relationship

• Individuals competing for a limited resource

• One species benefiting while the other is harmed

• A mutual benefit between two species

In the context of predation, what role does the prey play?

• The organism that benefits from the relationship

• The organism that competes for resources

• The organism that provides shelter

• The organism that is consumed by the predator

What is an example of herbivory?

• A cow grazing on grass

• A fish cleaning a larger fish

• A bird eating insects

• A lion hunting a zebra

How does mutualism differ from other interactions?

• Both organisms benefit

• Neither organism is affected

• Both organisms are harmed

• Only one organism benefits

What is a characteristic of parasitism?

• Both organisms benefit

• One organism is unaffected

• One organism benefits while the other is harmed

• Both organisms are harmed

Which interaction involves one organism benefiting without affecting the other?

• Parasitism

• Commensalism

• Mutualism

• Competition

What is a common example of commensalism?

• A wolf hunting in a pack

• A bee pollinating a flower

• A remora fish attaching to a shark

• A bird cleaning a crocodile's teeth

Which interaction is similar to parasitism but does not harm the host?

• Mutualism

• Commensalism

• Competition

• Predation

What is the main difference between parasitism and commensalism?

• In commensalism, both organisms are unaffected

• In parasitism, one organism is harmed

• In commensalism, one organism is harmed

• In parasitism, both organisms benefit
