Biodiversity Concepts and Conservation

The video covers biodiversity and conservation biology, explaining the three main levels of biodiversity: species, genetic, and ecosystem diversity. It discusses the challenges in measuring biodiversity and the uneven distribution of species. The video also explores extinction, differentiating it from extra patient, and highlights human impacts accelerating extinction rates. Causes of biodiversity loss, such as habitat loss, pollution, and climate change, are examined. The benefits of biodiversity, including ecosystem stability and economic advantages like ecotourism, are discussed. Conservation biology basics, key laws like the Endangered Species Act, and community-based conservation efforts are also covered.

What are the three main levels of biodiversity?

• Species, Habitat, and Climate Diversity

• Species, Genetic, and Ecosystem Diversity

• Genetic, Habitat, and Climate Diversity

• Ecosystem, Habitat, and Species Diversity

What is the term for when a species disappears from a specific area but still exists elsewhere?

• Ecosystem Collapse

• Extirpation

• Extinction

• Endangerment

Which of the following is NOT a cause of biodiversity loss?

• Pollution

• Habitat Loss

• Natural Selection

• Overharvesting

How does biodiversity contribute to ecosystem stability?

• By increasing the number of predators

• By reducing the number of species

• By providing a variety of species that can adapt to changes

• By eliminating competition among species

What is ecotourism?

• Traveling to historical sites for education

• Traveling to natural sites to observe wildlife

• Traveling to urban areas for leisure

• Traveling to industrial sites for business

What is the purpose of the Endangered Species Act?

• To allow trading of endangered species

• To protect endangered species and their habitats

• To encourage deforestation

• To promote hunting of endangered species

What is captive breeding?

• Breeding plants in greenhouses

• Breeding animals for zoos

• Breeding animals in controlled environments

• Breeding animals in the wild

What is an umbrella species?

• A species that is invasive

• A species that provides shade

• A species that is used to protect other species

• A species that is endangered

What is a biodiversity hotspot?

• An area with no species diversity

• An area with high species diversity

• An area with low species diversity

• An area with only invasive species

How does community-based conservation benefit local communities?

• By reducing tourism

• By increasing pollution

• By generating revenue through ecotourism

• By promoting deforestation
