Junior Cycle Science Quiz: Conservation of Biodiversity
Score: 0
1. Conservation of Biodiversity

​
What is Biodiversity?
  • Biodiversity refers to the variety of all living organisms, including plants, animals, and microorganisms, as well as the ecosystems they form.
Why is Biodiversity Important?
  • Ecosystem Stability: Biodiversity ensures ecosystems remain stable and resilient to changes.
  • Resources: Provides materials for food, medicine, and shelter.
  • Services: Supports pollination, water purification, and climate regulation.
Threats to Biodiversity:
  1. Habitat destruction due to deforestation, urbanisation, and agriculture.
  2. Pollution, including air, water, and soil contamination.
  3. Overexploitation of resources like fishing and hunting.
  4. Climate change leading to habitat loss and species extinction.
Conservation Strategies:
  1. Protected Areas:
    • National parks and wildlife reserves protect habitats and species.
  2. Sustainable Practices:
    • Reduce overfishing, overhunting, and deforestation.
  3. Restoration Projects:
    • Replanting forests and restoring wetlands.
  4. Education and Awareness:
    • Teaching communities about the importance of biodiversity.

2. Contribution to Global Food ProductionRole of Biodiversity in Food Production:
  1. Pollinators:
    • Bees, butterflies, and birds pollinate crops, ensuring food production.
  2. Soil Health:
    • Microorganisms and decomposers recycle nutrients, improving soil fertility.
  3. Genetic Diversity:
    • Wild species provide genetic material for breeding resilient and high-yield crops.
Challenges to Global Food Production:
  1. Overuse of chemical fertilisers and pesticides damages ecosystems.
  2. Climate change affects crop growth and leads to unpredictable weather patterns.
  3. Monoculture farming reduces biodiversity and increases vulnerability to pests.
Solutions for Sustainable Food Production:
  1. Crop Rotation:
    • Reduces pests and improves soil health.
  2. Organic Farming:
    • Minimises chemical use and protects biodiversity.
  3. Agroforestry:
    • Combines trees and crops to promote ecosystem health.
  4. Aquaponics:
    • Combines fish farming with plant cultivation for efficient resource use.

3. Benefits People Obtain from EcosystemsEcosystem Services:
  1. Provisioning Services:
    • Food, fresh water, timber, and medicinal resources.
  2. Regulating Services:
    • Climate regulation, flood control, and water purification.
  3. Cultural Services:
    • Recreational, spiritual, and aesthetic benefits.
  4. Supporting Services:
    • Nutrient cycling, soil formation, and oxygen production.
Economic Benefits:
  • Biodiversity supports industries like agriculture, forestry, and tourism.
  • Healthy ecosystems reduce costs for water treatment and disaster recovery.
Health and Well-Being:
  • Natural environments improve mental health and provide recreational opportunities.

4. Summary
  • Conserving biodiversity is crucial for stable ecosystems, food security, and the health of the planet.
  • Sustainable agricultural practices enhance global food production while protecting ecosystems.
  • Ecosystem services provide essential resources and benefits for human survival and quality of life.

Questions:

​Q1: What is biodiversity?
A: Biodiversity is the variety of all living organisms, including plants, animals, microorganisms, and the ecosystems they form.
Q2: Why is biodiversity important for ecosystems?
A: Biodiversity ensures ecosystem stability, provides resources for food and medicine, and supports services like pollination and water purification.
Q3: Name three threats to biodiversity.
A: Habitat destruction, pollution, and climate change.
Q4: What is a national park, and how does it help conserve biodiversity?
A: A national park is a protected area that preserves natural habitats and species, helping maintain biodiversity.
Q5: How do pollinators contribute to global food production?
A: Pollinators like bees and butterflies help fertilise crops, ensuring fruit and seed production.
Q6: What role do microorganisms play in agriculture?
A: Microorganisms improve soil fertility by recycling nutrients and breaking down organic matter.
Q7: What is monoculture farming, and why is it harmful to biodiversity?
A: Monoculture farming involves growing a single crop, reducing biodiversity and increasing vulnerability to pests and diseases.
Q8: Name two sustainable farming practices.
A: Crop rotation and organic farming.
Q9: What are provisioning services provided by ecosystems?
A: Provisioning services include resources like food, fresh water, timber, and medicinal materials.
Q10: How do ecosystems regulate the climate?
A: Ecosystems regulate the climate by absorbing carbon dioxide, controlling temperatures, and preventing extreme weather events.
Q11: What are the cultural benefits of ecosystems?
A: Ecosystems provide recreational opportunities, spiritual value, and aesthetic enjoyment.
Q12: How does reforestation contribute to biodiversity conservation?
A: Reforestation restores habitats, increases tree cover, and supports species dependent on forests.
Q13: What is agroforestry?
A: Agroforestry is a farming practice that combines trees and crops to promote ecosystem health and sustainable agriculture.
Q14: Name one economic benefit of conserving biodiversity.
A: Biodiversity supports industries like agriculture, forestry, and tourism, boosting economic growth.
Q15: Why is educating communities about biodiversity important?
A: Education raises awareness about the importance of biodiversity and encourages sustainable practices to protect ecosystems.
