Biology Multiple Choice Questions on “In-situ and Ex-situ Conservation”.
1. How do urbanization and an increase in population affect biodiversity?
a) Making land more productive
b) Loss of flora and fauna
c) More growth of flora and fauna
d) Increasing land’s agricultural capability
Answer: b
Clarification: Urbanization means the increasing number of people that live in urban areas due to shifting from rural areas to urban areas. It affects the population density and leads to more loss of flora and fauna since more space for residence is occupied by humans.
2. What is the protection and conservation of species in their natural habitat called?
a) In-situ conservation
b) Ex-situ conservation
c) Off-site conservation
d) No conservation
Answer: a
Clarification: The on-site or the protection and conservation of species (genetic resources) in their natural habitat (populations of plant or animal species) is called in-situ conservation. Areas such as biosphere reserves, national parks, and wildlife sanctuaries are the places were in-situ conservation is done.
3. What is the protection and conservation of species outside their natural habitat called?
a) No conservation
b) Ex-situ conservation
c) On-site conservation
d) In-situ conservation
Answer: b
Clarification: The off-site or the protection and conservation of species (genetic resources) outside their natural habitat (populations of plant or animal species) is known as ex-situ conservation. Areas such as botanical gardens, zoos, Gene banks, Tissue culture banks are the places were ex-situ conservation is done.
4. In which approach do we protect and conserve the whole ecosystem to protect the endangered species?
a) Ex-situ conservation
b) Off-site conservation
c) No conservation
d) In-situ conservation
Answer: d
Clarification: The on-site or the protection and conservation of species (genetic resources) in their natural habitat (populations of plant or animal species) is called in-situ conservation. In this, we conserve and protect the whole ecosystem for the protection of endangered species.
5. In which approach do we protect and conserve the animals that need urgent measures to save it from extinction?
a) In-situ conservation
b) On-site conservation
c) Ex-situ conservation
d) No conservation
Answer: c
Clarification: The off-site or the protection and conservation of species (genetic resources) outside their natural habitat (populations of plant or animal species) is known as ex-situ conservation. It is the approach in which we protect and conserve the animals that need urgent measures to save it from extinction.
6. What are the species confined to a particular region and not found anywhere else called?
a) Pandemic
b) Endemic
c) Extinct
d) Vulnerable
Answer: b
Clarification: Endemism is the ecological state of the species being confined to a particular region or only in one geographic region and not found anywhere else. Such species are known as endemic species. Some examples are Asiatic lion, Purple frog, Sangai deer, Sapria Himalayana, etc.
7. How many total biodiversity hotspots are present throughout the world?
a) 20
b) 80
c) 55
d) 34
Answer: d
Clarification: A biogeographic region with significant levels of biodiversity having a large number of endemic species that are threatened by human habitation is known as biodiversity hotspots. In all, there are 34 biodiversity hotspots present throughout the world.
8. Which of the following is an odd one?
a) Corbett National Park
b) Ghana Bird Sanctuary
c) Western Ghats
d) Andaman and Nicobar Islands
