IB Biology Unity and Diversity Quiz - Biodiversity

What is biodiversity?

• Number of species in a specific area

• The process of evolution

• The study of rocks and minerals

• Variety of life on Earth

Explain the difference between species diversity and genetic diversity.

• Species diversity is the variety of different species in a specific area, while genetic diversity is the variety of genes within a species.

• Species diversity is the variety of different species within a gene, while genetic diversity is the variety of genes within a species.

• Species diversity is the variety of different genes within a species, while genetic diversity is the variety of different species in a specific area.

• Species diversity is the variety of genes within a species, while genetic diversity is the variety of different species in a specific area.

Why is biodiversity important for ecosystems?

• It leads to ecosystem instability

• It contributes to ecosystem stability, resilience, and productivity.

• It decreases ecosystem productivity

• It has no impact on ecosystem stability

What are the main threats to biodiversity?

• Alien invasion, nuclear war, asteroid impact

• Habitat destruction, climate change, pollution, overexploitation, and invasive species

• Overpopulation, deforestation, urbanization

• Lack of sunlight, excessive rainfall, low temperature

Describe the concept of keystone species and its role in maintaining biodiversity.

• Keystone species play a crucial role in maintaining the balance and diversity of an ecosystem.

• Keystone species are only found in marine environments

• Keystone species have no impact on biodiversity

• Keystone species only exist in artificial ecosystems

How does habitat destruction contribute to the loss of biodiversity?

• Habitat destruction has no impact on the biodiversity of an area.

• Habitat destruction increases the available living space and resources for various species, leading to their growth and expansion.

• Habitat destruction only affects a few species, not the overall biodiversity.

• Habitat destruction reduces the available living space and resources for various species, leading to their decline or extinction.

Discuss the importance of biodiversity for human health and well-being.

• Biodiversity only affects the health of non-human species

• Human health and well-being are not affected by the loss of biodiversity

• Biodiversity has no impact on human health and well-being

• Biodiversity provides essential ecosystem services for human health and well-being.

Explain the concept of ecosystem services and how they are related to biodiversity.

• Ecosystem services are the benefits that humans receive from ecosystems, and they are related to biodiversity as biodiversity ensures the stability and resilience of ecosystems to provide these services.

• Ecosystem services are the benefits that humans receive from technology, and they are related to biodiversity as biodiversity has no impact on the services.

• Ecosystem services are the benefits that humans receive from industry, and they are related to biodiversity as biodiversity is not important for the provision of these services.

• Ecosystem services are the benefits that humans receive from urbanization, and they are related to biodiversity as biodiversity only affects non-essential services.

What are some conservation strategies to protect biodiversity?

• Introducing non-native species to new environments

• Clearing large areas of land for urban development

• Creating and managing protected areas, implementing sustainable land use practices, controlling invasive species, and promoting public awareness and education

• Hunting and capturing endangered species for display in zoos

Discuss the impact of climate change on biodiversity.

• Climate change can lead to habitat loss, changes in temperature and precipitation patterns, and increased frequency of extreme weather events, all of which can have significant impacts on biodiversity.

• Biodiversity increases with climate change

• Climate change only affects human populations

• Climate change has no impact on biodiversity
