Introduction to Biodiversity (Pre-test)

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What are keystone species?

Back

Keystone species are species that have a disproportionately large effect on their environment relative to their abundance. Their presence is critical for maintaining the structure of an ecological community.

Front

How does climate change affect biodiversity?

Back

Climate change impacts biodiversity by causing shifts in species distribution, altering habitats, and leading to extinction of vulnerable species.

Front

What is a conservation strategy for biodiversity?

Back

Creating protected areas like national parks and wildlife reserves is a key conservation strategy that helps preserve habitats and protect species.

Front

What is the impact of deforestation on biodiversity?

Back

Deforestation reduces habitat for many species, leading to decreased biodiversity and increased risk of extinction.

Front

Why is overexploitation a threat to biodiversity?

Back

Overexploitation threatens biodiversity by depleting resources that species depend on for survival, leading to population declines and potential extinction.

Front

What is habitat fragmentation?

Back

Habitat fragmentation occurs when large habitats are divided into smaller, isolated patches, which can negatively affect species' ability to survive and reproduce.

Front

What role do invasive species play in biodiversity?

Back

Invasive species can disrupt local ecosystems, outcompete native species, and lead to declines in biodiversity.

Front

What is the significance of genetic diversity?

Back

Genetic diversity is important for the adaptability and resilience of species, allowing them to survive changes in the environment.

Front

What are ecosystem services?

Back

Ecosystem services are the benefits that humans derive from ecosystems, including clean air, water purification, pollination, and climate regulation.
