- B. ethical value
- C. artificial selection
- D. competitive exclusion
Which conservation argument values species because they may provide food, medicines, fibres, or other direct products?
- A. Narrowly utilitarian value
- B. Ethical value only
- C. Competitive exclusion between species using the same limiting ecological resource
- D. Genetic drift
Direct products such as food, fuel, fibre and medicines illustrate:
- A. genetic drift
- B. ethical value only
- C. co-extinction
- D. narrowly utilitarian value
Ecosystem functions that support human well-being illustrate:
- A. founder effect
- B. biopiracy
- C. narrowly utilitarian value only
- D. broadly utilitarian value
Pollination, oxygen production, and climate regulation support which reason for conserving biodiversity?
- A. Only aesthetic preference
- B. Broadly utilitarian value
- C. Random genetic change
- D. Taxonomic convenience
A forest species provides a compound later developed into an important medicine. This illustrates which argument for biodiversity conservation?
- A. Direct utilitarian value
- B. No economic value
- C. Only aesthetic value
- D. Only geological value
A wetland buffers floods, filters water and supports nutrient cycling even though these services are not bought and sold directly. This supports conservation because of
- A. ecosystem service value
- B. absence of ecological value
- C. only recreational value
- D. only taxonomic interest
A person argues that a species should be protected because humans have no right to knowingly drive another species to extinction. This is primarily a
- A. moral or ethical argument
- B. purely market-price argument
- C. measurement-error argument
- D. population-growth equation
Why can conserving genetically diverse wild relatives of crops be valuable?
- A. They may contain alleles useful for future breeding, disease resistance or climate adaptation
- B. They always reduce crop genetic diversity
- C. They eliminate the need for plant breeding
- D. They cannot contribute any useful traits
Why does the ethical argument for biodiversity conservation differ from a purely economic argument?
- A. It rejects every human use of nature
- B. Only species with a measurable current market value deserve long-term conservation
- C. Species have value beyond immediate human use
- D. It measures biodiversity only by market price
Common mistakes in Reasons for conserving biodiversity
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Treats lack of present knowledge as evidence that a species has no value.
- Assumes species can be conserved independently of their habitat and interactions.
- Reduces biodiversity value to a single currently traded product.
