Biodiversity and Ecosystem Stability: The Interconnected Web of Life

The video explores biodiversity and its critical role in ecosystem stability. It defines biodiversity as the variety of life forms on Earth, resulting from millions of years of evolution. The importance of biodiversity is highlighted, emphasizing its contribution to ecosystem health and resilience. The video discusses ecosystem services like pollination and climate regulation, and the role of keystone species. It addresses human impacts such as deforestation and pollution, and the need for conservation efforts. The video concludes with a call to action to protect biodiversity.

What is biodiversity?

• The variety of life forms on Earth

• The study of ecosystems

• The process of evolution

• The impact of humans on nature

Why is biodiversity important for ecosystems?

• It reduces the number of species in an ecosystem

• It helps ecosystems resist and adapt to changes

• It increases the number of predators

• It makes ecosystems more visually appealing

Which of the following is an example of an ecosystem service?

• Pollination

• Deforestation

• Urbanization

• Mining

What role do keystone species play in an ecosystem?

• They are the most numerous species

• They have a large impact on their environment

• They are the least important species

• They have a minor impact on their environment

How does high biodiversity contribute to ecosystem stability?

• By making ecosystems more vulnerable

• By increasing the chances of species adapting to changes

• By eliminating disturbances

• By reducing the number of species

What is the difference between resistance and resilience in ecosystems?

• Resistance is the ability to withstand, resilience is to bounce back

• Both mean the same thing

• Neither is related to biodiversity

• Resistance is the ability to bounce back, resilience is to withstand

What human activities are threatening biodiversity?

• Nutrient cycling

• Conservation efforts

• Pollination

• Deforestation and pollution

What can loss of biodiversity lead to?

• Destabilized ecosystems

• Stabilized ecosystems

• Increased human well-being

• More biodiversity

What is one of the goals of conservation efforts?

• To increase pollution

• To restore biodiversity

• To destroy habitats

• To reduce the number of species

How can individuals contribute to biodiversity conservation?

• By ignoring environmental issues

• By raising awareness about its importance

• By promoting unsustainable practices

• By supporting habitat destruction
