LOSS OF BIODIVERSITY - CAUSES (HIPPO) - UNSOLVED PRACTICE SET
Topic: Loss of Biodiversity Causes HIPPO
Multiple Choice Questions
Q1. The HIPPO framework is commonly used to summarise the major causes of:
- Population growth in wildlife species
- Biodiversity loss
- Increased species richness
- Successful conservation efforts
Q2. In the HIPPO framework, the letter "H" stands for:
- Human population growth
- Habitat loss and fragmentation
- Hunting only
- Hybridisation
Q3. Invasive species, one of the factors in the HIPPO framework, threaten native biodiversity mainly by:
- Providing additional food sources for native species
- Outcompeting, preying upon, or otherwise disrupting native species and ecosystems
- Having no ecological impact at all
- Always coexisting peacefully with native species
Q4. Overexploitation, as a cause of biodiversity loss, refers to:
- The sustainable use of natural resources within ecological limits
- The excessive and unsustainable harvesting or hunting of species beyond their capacity to recover
- The complete protection of all species from any human use
- A factor unrelated to species decline
Q5. According to the HIPPO framework, unchecked human population growth contributes to biodiversity loss mainly by:
- Reducing demand for natural resources
- Increasing demand for land, resources, and habitat conversion, placing greater pressure on ecosystems
- Having no impact on natural ecosystems
- Automatically protecting more habitats
Short Answer Questions
Q6. What does the acronym HIPPO stand for in the context of biodiversity loss?
Q7. Explain how habitat loss and fragmentation contribute to declining biodiversity.
Q8. Give one example of how an invasive species can threaten native biodiversity.
Q9. How does pollution, as a factor in the HIPPO framework, negatively affect biodiversity?
Long Answer Questions
Q10. Discuss the HIPPO framework of biodiversity loss, explaining each of its five components and how they collectively threaten global biodiversity.
Q11. Explain how overexploitation and human population growth, as two separate but related factors, contribute to the ongoing loss of biodiversity worldwide.
APPLICATION / ANALYSIS
Q12. A wetland ecosystem experiences habitat fragmentation due to nearby urban development, is invaded by a non-native aquatic plant species, and receives agricultural runoff pollution from nearby farms. Identify which components of the HIPPO framework are affecting this wetland, and explain how their combined effects might be more damaging than any single factor alone.
Q13. A particular species of fish has been heavily overfished for decades to meet rising demand from a growing human population, leading to a sharp decline in its numbers. Explain how this scenario illustrates the connection between two components of the HIPPO framework - overexploitation and population growth.
