What is biodiversity?
Biodiversity refers to the variety of life in a given area, including species diversity, genetic diversity, and ecosystem diversity.
Why is biodiversity important?
It enhances ecosystem productivity, stability, and resilience, providing essential services like food, clean water, and medicine.
True or false: Biodiversity only refers to plant life.
False, because biodiversity includes animals, fungi, and microorganisms as well.
Difference between species diversity and genetic diversity
Species diversity measures the variety of species in an area, while genetic diversity refers to the variations within a species.
Fill the blank: Ecosystem services include __________.
Provisioning (food), regulating (climate), cultural (recreational), and supporting (nutrient cycling) services.
What is an ecosystem?
An ecosystem is a community of living organisms and their physical environment, interacting as a system.
Question: How does habitat destruction affect biodiversity?
It leads to loss of species and genetic diversity, disrupting ecosystem balance.
True or false: Biodiversity can reduce the spread of diseases.
True, because diverse ecosystems can limit pathogen transmission.
What are invasive species?
Invasive species are non-native organisms that disrupt local ecosystems, often outcompeting native species.
Why does biodiversity provide resilience?
Diverse ecosystems are better at adapting to changes and disturbances, ensuring stability.
Question: What is the role of pollinators?

True, because more species can perform various functions.
Question: Name a benefit of protecting biodiversity.
It ensures sustainable resources, ecological balance, and cultural identity.
Difference between renewable and non-renewable resources
Renewable resources can be replenished naturally, while non-renewable resources are finite.
What is ecological footprint?
It measures human demand on Earth's ecosystems, indicating how much land and water is needed.
True or false: Climate change has no effect on biodiversity.
False, because climate change can alter habitats and species distributions.
