Biodiversity and Its Importance

Biodiversity is crucial in ecology, representing the variety of life forms in different areas. It is measured at genetic, species, and ecosystem levels, with the highest diversity near the equator. Biodiversity is declining due to factors like climate change and human activities, leading to the current Holocene extinction. Conservation efforts, such as better land management and urban biodiversity enhancement, are vital to mitigate biodiversity loss and maintain ecosystem services.

What is biodiversity primarily concerned with?

• The number of different life forms in an area

• The amount of rainfall in a region

• The temperature variations in an ecosystem

• The size of the largest species in an area

What is a key concept in ecology that has importance on both local and global scales?

• Climate change

• Urbanization

• Biodiversity

• Deforestation

Where is biodiversity generally the highest?

• At the equator

• In urban areas

• In desert regions

• At the poles

What is the current major extinction event called?

• Permian extinction

• Cretaceous extinction

• Holocene extinction

• Triassic extinction

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

• Volcanic eruptions

• Introduction of rabbits to Australia

• Natural forest fires

• Seasonal changes

How does the decline of bees affect human society?

• It reduces the pollination of crops

• It causes more rainfall

• It leads to more forest fires

• It increases the number of flowers

What is one way to increase biodiversity in urban areas?

• Reducing the number of parks

• Building more skyscrapers

• Creating spaces for other species

• Increasing the number of cars

What is a benefit of a healthy and diverse ecosystem?

• It reduces the number of plant species

• It increases the number of predators

• It can withstand and recover from disasters

• It causes more natural disasters

Which of the following is NOT a way to reduce biodiversity loss?

• Managing land better

• Creating urban green spaces

• Growing a single type of crop

• Encouraging insect diversity

What is one of the free services provided by a healthy biodiverse ecosystem?
