Understanding Habitats, Niches, and Symbiotic Relationships in Ecology

The video tutorial explains the concepts of habitat and niche, highlighting their differences and significance. It introduces symbiotic relationships, focusing on parasitism, commensalism, and mutualism, with examples for each. The importance of species occupying different niches to reduce competition is discussed, along with the benefits of forming symbiotic relationships for survival.

What is the primary difference between a habitat and a niche?

• A habitat is where an organism lives, while a niche is its role in the environment.

• A niche is where an organism lives, while a habitat is its role in the environment.

• A habitat is the food an organism eats, while a niche is its predator.

• A niche is the food an organism eats, while a habitat is its predator.

Why is it beneficial for species to occupy different niches?

• To reduce competition for resources.

• To live in the same habitat.

• To increase competition for resources.

• To share the same food sources.

Which of the following is NOT a type of symbiotic relationship?

• Predation

• Mutualism

• Parasitism

• Commensalism

In commensalism, how does one organism benefit?

• Both organisms benefit.

• One organism benefits while the other is harmed.

• Neither organism benefits.

• One organism benefits while the other is neither harmed nor benefited.

What is an example of mutualism?

• A hummingbird catching a ride with a larger bird.

• A bee pollinating a flower while collecting nectar.

• A lion hunting a zebra.

• A tapeworm in a human's intestine.

Which relationship involves one organism benefiting at the expense of another?

• Commensalism

• Mutualism

• Parasitism

• Cooperation

How does a hummingbird benefit in a commensal relationship?

• It helps the larger bird find food.

• It cleans the larger bird's feathers.

• It saves energy by catching a ride.

• It gets food from the larger bird.
