Biodiversity

The video discusses biodiversity across the planet, highlighting the variety of species and genetic variation within them. It emphasizes the importance of high biodiversity for maintaining healthy and stable ecosystems, particularly in terrestrial habitats. The video also contrasts the rich biodiversity of tropical regions with the limited species found in polar areas.

What does biodiversity encompass?

• The variety of species and their variations

• Only the number of species

• Only the genetic differences within species

• The number of ecosystems

Why is high biodiversity considered crucial for ecosystems?

• It reduces the number of species in an area

• It ensures the dominance of a single species

• It leads to more competition among species

• It contributes to the health and stability of ecosystems

Which regions are known for having high biodiversity?

• Tropical regions

• Urban areas

• Desert regions

• Polar regions

How do polar regions compare to tropical regions in terms of biodiversity?

• Polar regions support fewer species

• Tropical regions have fewer species

• Polar regions have more species

• Both have the same number of species

What is a characteristic of tropical regions regarding biodiversity?

• They are similar to polar regions in biodiversity

• They have no variation within species

• They are typically richly biodiverse

• They have a limited number of species
