- What is the primary goal of wildlife corridors?
a) To provide animals with a safe space for reproduction
b) To connect fragmented habitats
c) To offer protection from predators
d) To increase human access to natural areas
Answer: b) To connect fragmented habitats
Explanation: Wildlife corridors are designed to link fragmented habitats, allowing animals to move between areas and access food, mates, and resources, thus promoting biodiversity.
- Which of the following is the most effective way to prevent species extinction?
a) Introducing new species into ecosystems
b) Establishing protected areas
c) Increasing pollution control measures
d) Encouraging habitat fragmentation
Answer: b) Establishing protected areas
Explanation: Creating protected areas like wildlife sanctuaries and national parks is one of the most effective ways to prevent species extinction by conserving their natural habitats.
- Which type of species is most vulnerable to extinction?
a) Species with wide geographic ranges
b) Species with large populations
c) Endemic species with small populations
d) Species with high reproductive rates
Answer: c) Endemic species with small populations
Explanation: Endemic species with small populations are more vulnerable to extinction due to their limited range and smaller genetic diversity, making them more susceptible to environmental changes.
- Which of the following ecosystems is known as a “carbon sink” due to its ability to store large amounts of carbon?
a) Deserts
b) Tropical rainforests
c) Grasslands
d) Coral reefs
Answer: b) Tropical rainforests
Explanation: Tropical rainforests act as significant carbon sinks by absorbing and storing carbon dioxide through photosynthesis, playing a vital role in regulating the global carbon cycle.
- Which of the following is an indirect value of biodiversity?
a) Food production
b) Climate regulation
c) Timber extraction
d) Medicinal resources
Answer: b) Climate regulation
Explanation: Indirect values of biodiversity include ecosystem services such as climate regulation, nutrient cycling, and pollination, which benefit human well-being without directly using biodiversity.
- Which of the following international agreements focuses on biodiversity conservation?
a) Kyoto Protocol
b) Paris Agreement
c) Convention on Biological Diversity (CBD)
d) Montreal Protocol
Answer: c) Convention on Biological Diversity (CBD)
Explanation: The Convention on Biological Diversity (CBD) is an international treaty aimed at conserving biodiversity, promoting sustainable use, and ensuring the fair sharing of genetic resources.
- The introduction of non-native species into an ecosystem often results in:
a) An increase in biodiversity
b) Stabilization of the ecosystem
c) A threat to native species
d) No significant impact on the ecosystem
Answer: c) A threat to native species
Explanation: Non-native (invasive) species often outcompete native species for resources, disrupt ecosystems, and can lead to declines or extinction of native species.
- Which of the following species is an example of a keystone species?
a) Sea otter
b) House cat
c) Goldfish
d) Cow
Answer: a) Sea otter
Explanation: Sea otters are considered keystone species because they play a critical role in maintaining the structure of their ecosystem by controlling sea urchin populations, which in turn protect kelp forests.
- Which of the following is an example of a flagship species used to promote conservation?
a) Antelope
b) Snow leopard
c) Cockroach
d) Barn owl
Answer: b) Snow leopard
Explanation: Flagship species like the snow leopard are charismatic animals used in conservation campaigns to raise public awareness and support for conservation efforts.
- Which of the following approaches is a key element of in situ conservation?
a) Breeding endangered species in captivity
b) Creating national parks and wildlife reserves
c) Growing plants in botanical gardens
d) Storing seeds in seed banks
Answer: b) Creating national parks and wildlife reserves
Explanation: In situ conservation focuses on protecting species in their natural habitats by creating protected areas such as national parks and wildlife reserves.
