2010 HIGHER SCHOOL CERTIFICATE EXAMINATION Question: Describe the importance of biodiversity in an ecosystem - HSC - SSCE Biology - Question 1 - 2010 - Paper 1

Biodiversity is crucial to the health and stability of ecosystems. It enhances productivity, resilience, and adaptability. A diverse ecosystem can better withstand environmental changes and disturbances, such as climate change or natural disasters.

1. Ecological Balance: Biodiversity contributes to the balance of ecosystems through complex interdependencies among species. Different organisms fill various niches, ensuring that resources are utilized sustainably.

2. Economic Benefits: Healthy ecosystems provide a range of resources, including food, raw materials, and medicines. Many industries, such as agriculture and pharmaceuticals, rely on biodiversity.

3. Cultural Significance: Biodiversity is often tied to cultural identity, offering recreational opportunities and spiritual value for communities.

4. Pollination and Soil Fertility: Many species, including insects and birds, are essential for pollination and maintaining soil health. Their absence can lead to agricultural declines.

In summary, preserving biodiversity is vital for maintaining ecosystem services, ensuring human well-being, and fostering a sustainable environment.
