Biodiversity and Genetic Diversity Concepts

The video tutorial covers the topic of biodiversity, starting with the plight of Siberian Tigers and the impact of poaching. It explains the concept of biodiversity, species classification, and genetic diversity, highlighting the importance of genetic variation for adaptation and survival. The tutorial also discusses ecosystem diversity, speciation, and the uneven distribution of species across the globe. It concludes with the challenges of measuring biodiversity and the factors affecting species richness.

What is the primary reason for the decline in the Siberian Tiger population?

• Climate change

• Habitat loss

• Poaching

• Disease

Which organization is involved in the conservation of Siberian Tigers?

• Greenpeace

• World Wildlife Fund

• Wildlife Conservation Society

• National Geographic Society

What does biodiversity encompass?

• Only animal species

• Only microorganisms

• All organisms in an area, including their genes and ecosystems

• Only plant species

How do taxonomists classify species?

• By their appearance and genetic makeup

• By their color

• By their habitat

• By their size

What is genetic diversity?

• The variety of ecosystems in a region

• The number of genes in a species

• The difference in DNA among individuals within a population

• The number of species in an area

Why is genetic diversity important for species?

• It increases their size

• It makes them more aggressive

• It helps them to adapt to changing conditions

• It makes them more colorful

What is ecosystem diversity?

• The variety of animals in a zoo

• The variety of ecosystems in a specific area

• The number of species in a forest

• The number of trees in a jungle

Which area is likely to have more biodiversity?

• A desert

• A city park

• A monoculture corn field

• A mountain slope with varied vegetation

What is the latitudinal gradient?

• The increase in species richness closer to the equator

• The variation in rainfall across latitudes

• The change in temperature with altitude

• The change in daylight hours with latitude

How can human disturbances sometimes increase biodiversity?

• By increasing pollution

• By creating habitat heterogeneity

• By introducing new species

• By reducing competition
