Biodiversity and Invasive Species Concepts

Mr. Turner discusses biodiversity, invasive species, and their impacts on ecosystems. He explains the levels of biodiversity, the role of keystone species, and the threats posed by invasive species. The video also covers areas of critical biodiversity and legal protections for endangered species. Students are assigned tasks related to Florida's invasive species.

What is the main focus of Mr. Turner's lesson this week?

• Biodiversity and Invasive Species

• Mathematics and Algebra

• Physics and Quantum Mechanics

• History and Ancient Civilizations

Approximately how many species are known to science?

• 50 million

• 500,000

• 10 million

• 1.7 million

Which level of biodiversity involves the variety of habitats and ecological processes?

• Population Diversity

• Ecosystem Diversity

• Genetic Diversity

• Species Diversity

What is a keystone species?

• A species that is the most colorful

• A species that is the fastest

• A species that is critical to the functioning of an ecosystem

• A species that is the largest in its ecosystem

What is the difference between endangered and threatened species?

• Threatened species are extinct, endangered species are not

• Endangered species are in danger of extinction now, threatened species may become endangered soon

• Endangered species are extinct, threatened species are not

• Threatened species are in danger of extinction now, endangered species may become threatened soon

What defines an invasive species?

• A species that is native to an area

• A species that causes harm to its new environment

• A species that is beneficial to its new environment

• A species that is the largest in its new environment

Why do invasive species often thrive in new environments?

• They are more colorful

• They are larger in size

• They have fewer predators

• They have more predators

What is an endemic species?

• A species found worldwide

• A species that is invasive

• A species found only in a specific location

• A species that is extinct

Which areas are considered biodiversity hotspots?

• Deserts and tundras

• Tropical rainforests and coastal areas

• Urban cities

• Mountain ranges

What is the purpose of the Endangered Species Act?

• To protect species in danger of extinction

• To promote hunting of endangered species

• To classify new species

• To increase the population of invasive species
