4.1.3 Importance of Biodiversity

• Biodiversity refers to the variety of life forms present on Earth
• Arrange the three key components of biodiversity in their correct order.

  1️⃣ Genetic Diversity

  2️⃣ Species Diversity

  3️⃣ Ecosystem Diversity
• The three components of biodiversity are interconnected and vital for maintaining healthy and resilient ecosystems.
• Genetic diversity refers to the range of genes within a species or population.
• Species diversity refers to the variety of species in an ecosystem.
• Ecosystem diversity includes the variety of habitats, communities, and ecological processes.
• What does genetic diversity allow species to do?

  Adapt to changes
• Species diversity provides ecosystem stability and resilience by ensuring multiple species can perform similar functions.
• Ecosystem diversity maintains ecosystem services and supports ecological processes.
• Diverse tree species in a forest ecosystem help maintain soil quality through different root systems.
• How does biodiversity enhance agriculture?

  Crop resilience and yield
• Biodiversity provides natural compounds for drug development in the field of medicine.
• Why does biodiversity attract visitors to biodiverse areas?

  Ecotourism
• What does biodiversity refer to?

  Variety of life on Earth
• Genetic diversity ensures species can adapt to changing environments
• What does species diversity in an ecosystem provide?

  Stability and resilience
• Why is genetic diversity ecologically important?

  Adaptation to change
• Species diversity stabilizes ecosystem functions
• What ecosystem service is maintained by ecosystem diversity?

  Carbon sequestration
• A diverse forest can withstand disease outbreaks more effectively than a uniform forest.
• Match the biodiversity component with its ecological importance:

  Genetic Diversity ↔️ Enhances adaptation to change

  Species Diversity ↔️ Ensures ecosystem resilience

  Ecosystem Diversity ↔️ Maintains vital ecosystem services
• How does biodiversity enhance agriculture?

  Improves crop resilience
• Biodiversity provides natural compounds for drug development
• What role does biodiversity play in tourism?

  Attracts visitors
• Biodiversity has both cultural and aesthetic importance.
• Match the importance type with its description:

  Cultural Importance ↔️ Integral to folklore and traditions

  Aesthetic Importance ↔️ Inspires art and recreation
• What is an example of cultural importance of biodiversity?

  Sacred forests
• Diverse wildlife in national parks promotes ecotourism
• What is the medicinal importance of biodiversity?

  Natural drug development
• Match the drug with its origin and use:

  Penicillin ↔️ Fungi (Penicillium), antibiotic

  Morphine ↔️ Poppy plant, pain relief

  Paclitaxel (Taxol) ↔️ Yew tree, chemotherapy

  Streptomycin ↔️ Bacteria (Streptomyces), antibiotic
• What are ecosystem services provided by biodiversity?

  Benefits from natural ecosystems
• Pollination is an example of an ecosystem service that supports crop production.
• Wetlands provide water purification
• How do forests regulate climate?

  Store carbon dioxide
• Maintaining biodiversity is essential to ensure ecosystem services continue to support human well-being.
• What is the primary definition of biodiversity?

  Variety of life forms
• One key component of biodiversity is genetic diversity
• Biodiversity includes genetic, species, and ecosystem diversity.
• What is an example of genetic diversity within a species?

  Different coat colors in rabbits
• Species diversity refers to the variety of species in an ecosystem
