Click on the flashcard to see the answer


What is biodiversity?

Biodiversity refers to the variety of living organisms in a particular area or on the entire planet.

Why is biodiversity important?

Biodiversity is important as it contributes to ecosystem stability, provides essential resources, and has aesthetic and cultural value.

What are the main threats to biodiversity?

The main threats to biodiversity include habitat loss, pollution, climate change, invasive species, and overexploitation.

What is habitat loss?

Habitat loss refers to the destruction or degradation of a natural habitat, leading to the displacement or extinction of species.

What is pollution?

Pollution is the introduction of harmful substances or contaminants into the environment, negatively affecting biodiversity.

What is climate change?

Climate change refers to long-term shifts in temperature and weather patterns, impacting biodiversity by altering habitats and ecosystems.

What are invasive species?

Invasive species are non-native organisms that disrupt ecosystems by outcompeting native species or causing ecological imbalances.

What is overexploitation?

Overexploitation refers to the excessive use or harvesting of natural resources, leading to the decline of certain species or ecosystems.

What are the benefits of biodiversity conservation?

Biodiversity conservation helps maintain ecosystem services, promotes sustainable development, and preserves genetic resources.

What is endangered species?

Endangered species are those facing a high risk of extinction in the wild unless significant conservation efforts are implemented.

What is the role of protected areas in biodiversity conservation?

Protected areas play a crucial role in safeguarding biodiversity by providing habitats for numerous species and conserving ecosystems.

What is the Convention on Biological Diversity (CBD)?

The Convention on Biological Diversity is an international treaty aimed at promoting sustainable development and conserving biodiversity.

What is the importance of genetic diversity?

Genetic diversity allows populations to adapt to changing environments, enhances species resilience, and supports ecosystem functions.

What are keystone species?

Keystone species have a disproportionate impact on their ecosystem, playing a critical role in maintaining the structure and function of the community.

What is the difference between biodiversity and species richness?

Biodiversity encompasses the variety of species, ecosystems, and genetic diversity, while species richness refers to the number of species in a particular area.
