Specialist and Generalist Species Characteristics

Mr. Smeeds discusses the differences between specialist and generalist species using raccoons and red pandas as examples. Specialist species, like red pandas, have narrow ecological tolerance and specific needs, making them less adaptable to changes. Generalist species, like raccoons, have broad ecological tolerance and varied diets, making them more adaptable and potentially invasive. The video covers learning objectives, essential knowledge, and concludes with practice questions on species characteristics.

Which species is considered a specialist due to its narrow range of tolerance and specific dietary needs?

• Raccoon

• Red Panda

• Panda Bear

• Koala

Which species is an example of a generalist due to its varied diet?

• Koala

• Panda Bear

• Red Panda

• Raccoon

What is the main advantage of generalist species in changing habitats?

• They have a specific food requirement.

• They have a narrow range of tolerance.

• They are less likely to be invasive.

• They can easily adapt to new food sources.

Why are generalist species more likely to become invasive?

• They are more prone to extinction.

• They have a narrow range of food sources.

• They are less adaptable to new environments.

• They can utilize a wide range of resources.

How does a broad niche benefit generalist species?

• It restricts their competitive ability.

• It allows them to adapt to various environments.

• It limits their food availability.

• It makes them more prone to extinction.

Which of the following is NOT a characteristic of generalist species?

• Potential to be invasive

• Broad food availability

• Narrow range of tolerance

• High adaptability

Which of the following is a characteristic of specialist species?

• Wide range of food sources

• Specific and specialized needs

• High adaptability

• Broad niche

What makes specialist species more likely to become endangered?

• Their ability to adapt to new conditions

• Their broad range of tolerance

• Their specific habitat and food requirements

• Their competitive nature

What is a disadvantage of specialist species when ecosystems are disturbed?

• They are more likely to be invasive.

• They are less adaptable to changes.

• They have a broad range of tolerance.

• They can easily switch to new resources.

What is the main focus of the conclusion in the video?

• Describing the habitat of red pandas

• Explaining why specialist species are more likely to become extinct

• Discussing the adaptability of raccoons

• Explaining the concept of generalist species
