Show answer & explanation
Correct answer: A — Biodiversity
Biodiversity is the variety of life in a particular habitat or ecosystem, encompassing genetic, species, and ecosystem diversity.
Q2. Which conservation strategy focuses on maintaining genetic resources outside their natural habitats?
Show answer & explanation
Correct answer: D — Ex-situ conservation
Ex-situ conservation involves conserving biodiversity outside its natural habitat, such as in botanical gardens or gene banks.
Q3. What is the primary role of biodiversity in providing essential ecosystem services?
Show answer & explanation
Correct answer: B — Maintaining ecological balance and resource availability
Biodiversity ensures the stability of ecosystems, which in turn provides essential services like regulating climate and providing clean water.
Q4. Which of the following terms refers to the variety of life found in a particular habitat or ecosystem?
Show answer & explanation
Correct answer: A — Species diversity
Species diversity refers to the variety of different species present in a particular area. Ecosystem diversity relates to the variety of different ecosystems. Genetic diversity refers to the variation within a single species.
Q5. Areas characterized by a high degree of endemic species and high rates of biodiversity are often termed:
Show answer & explanation
Correct answer: A — Biodiversity hotspots
Biodiversity hotspots are regions with a high concentration of endemic species that are under severe threat of habitat loss.
Q6. A region that harbors a high concentration of endemic species and is under severe threat of habitat loss is typically classified as a:
Show answer & explanation
Correct answer: B — Biodiversity hotspot
Biodiversity hotspots are recognized areas that have a large number of species but are severely threatened by habitat loss.
Q7. The loss of species due to habitat destruction is primarily an issue of which type of biodiversity loss?
Show answer & explanation
Correct answer: D — Species diversity loss
Habitat destruction directly leads to the loss of specific species, which is a primary measure of species diversity loss.
Q8. Which of the following terms represents the total variety of life forms found in a particular area, including genetic, species, and ecosystem diversity?
Show answer & explanation
Correct answer: C — Biodiversity
Biodiversity refers to the variety of life forms at all levels of biological organization, encompassing genetic diversity, species diversity, and ecosystem diversity.
Q9. Which category of conservation involves protecting species in controlled environments like zoos or botanical gardens?
Show answer & explanation
Correct answer: B — Ex situ conservation
Ex situ conservation involves protecting species outside their natural habitats, such as in captive breeding programs or botanical gardens.
Q10. Species richness is a measure of:
Show answer & explanation
Correct answer: D — The total number of species present in an area.
Species richness is the count or variety of different species present in a particular area.
Q11. Which of the following terms is used to describe the variety of life forms present in a particular area or ecosystem?
Show answer & explanation
Correct answer: C — Biodiversity
Biodiversity (Biological Diversity) refers to the variety of life forms at all levels of biological organization, including genetic variation, species diversity, and ecosystem diversity within a particular region.
Q12. Which of the following levels of biodiversity refers to the variety of genes within a single species?
Show answer & explanation
Correct answer: A — Genetic diversity
Genetic diversity refers to the variation of genes within a single population or species.
Q13. Habitat fragmentation primarily leads to which negative consequence for biodiversity?
Show answer & explanation
Correct answer: A — Reduced gene flow.
Habitat fragmentation breaks up continuous habitats, which restricts the movement of organisms and reduces gene flow between populations.
