BIOLOGY - Environment - What is biodiversity

The video discusses biodiversity, its measurement at genetic, species, and ecosystem levels, and the differences between global and local biodiversity. It highlights the highest biodiversity at the equator and the lowest at the poles. The video explains factors affecting biodiversity, including climate change and human activities, leading to the current Holocene extinction. It emphasizes the consequences of biodiversity loss, such as the decline of pollinators like bees, and suggests strategies to enhance biodiversity, including better land management and urban planning.

Where is biodiversity typically the highest?

• In urban areas

• At the equator

• In desert regions

• At the poles

What is the current major extinction event called?

• Permian extinction

• Cretaceous extinction

• Triassic extinction

• Holocene extinction

Which of the following is an example of an anthropogenic factor affecting biodiversity?

• Natural disasters

• Invasive species introduction

• Volcanic eruptions

• Solar flares

Why is biodiversity important for ecosystems?

• It makes ecosystems more uniform

• It reduces the number of species

• It helps ecosystems recover from disasters

• It increases the number of predators

What is one way urban areas can contribute to biodiversity conservation?

• By increasing pollution

• By focusing only on rural biodiversity

• By reducing green spaces

• By creating spaces for other species
