**Question 1.** Which level of biodiversity refers to the variety of genes within a species?
A) Ecosystem diversity
B) Species diversity
C) Genetic diversity
D) Functional diversity
Answer: C
Explanation: Genetic diversity is the variation of genes within a species, providing the raw
material for evolution and adaptation.
**Question 2.** A region that contains a high number of endemic species and is under
significant threat is known as a:
A) Biodiversity hotspot
B) Conservation corridor
C) Wilderness area
D) Ecological niche
Answer: A
Explanation: Biodiversity hotspots are areas with exceptional levels of endemic species that face
high levels of habitat loss.
**Question 3.** Which type of species is most likely to have a disproportionately large effect on
its ecosystem relative to its abundance?
A) Umbrella species
B) Indicator species
C) Keystone species
D) Flagship species
Answer: C
, AIEHS Certified Chief Biodiversity Conservation
Officer CCBCO Exam
Explanation: Keystone species play a critical role in maintaining the structure of an ecological
community, and their removal can cause dramatic changes.
**Question 4.** The provision of clean drinking water to humans is classified under which
ecosystem service category?
A) Cultural services
B) Regulating services
C) Supporting services
D) Provisioning services
Answer: D
Explanation: Provisioning services are the tangible goods obtained from ecosystems, such as
water, food, and timber.
**Question 5.** Which ecosystem service helps mitigate climate change by removing carbon
dioxide from the atmosphere?
A) Pollination
B) Soil formation
C) Climate regulation
D) Recreational opportunities
Answer: C
Explanation: Climate regulation includes carbon sequestration, which reduces atmospheric CO₂
concentrations.
**Question 6.** A GIS layer that displays the distribution of a particular forest type is primarily
used for:
A) Species inventory
B) Habitat mapping
, AIEHS Certified Chief Biodiversity Conservation
Officer CCBCO Exam
C) Genetic analysis
D) Climate modeling
Answer: B
Explanation: GIS habitat mapping visualizes spatial distribution of ecosystems, aiding in planning
and monitoring.
**Question 7.** Which surveying method is most suitable for detecting cryptic amphibian
species in a wetland?
A) Line transect sampling
B) Pitfall traps
C) Audio call surveys
D) Aerial photography
Answer: C
Explanation: Audio call surveys capture species-specific vocalizations, effective for elusive
amphibians.
**Question 8.** Gap analysis in conservation planning is used to:
A) Identify genetic mutations in populations
B) Locate unprotected high‑value habitats
C) Measure ecosystem service output
D) Assess climate change vulnerability
Answer: B
Explanation: Gap analysis compares existing protected areas with biodiversity features to find
conservation gaps.
**Question 9.** The primary objective of ex‑situ conservation is to:
, AIEHS Certified Chief Biodiversity Conservation
Officer CCBCO Exam
A) Preserve ecosystems in their natural location
B) Maintain species outside their natural habitats
C) Restore degraded habitats in situ
D) Increase carbon sequestration on farms
Answer: B
Explanation: Ex‑situ conservation involves conserving components of biodiversity outside their
natural settings, such as seed banks.
**Question 10.** Seed banks contribute to biodiversity conservation by:
A) Reintroducing predators into ecosystems
B) Preserving genetic material for future use
C) Monitoring wildlife migration routes
D) Controlling invasive plant species
Answer: B
Explanation: Seed banks store genetic material, safeguarding plant diversity against extinction.
**Question 11.** Which protected‑area category under the IUCN focuses on ecosystem
protection with limited human use?
A) Category Ia – Strict Nature Reserve
B) Category II – National Park
C. Category III – Natural Monument
D. Category VI – Protected area with sustainable use
Answer: A
Explanation: Category Ia reserves aim for strict protection of biodiversity and geological features
with minimal human interference.
