In-situ conservation primarily aims to protect species by:
- A Preserving them well outside of their natural habitats
- B Maintaining them within their natural ecosystems
- C Storing their genetic material in laboratories
- D Artificially increasing their mutation rates
Correct answer: Maintaining them within their natural ecosystems
In-situ conservation focuses on protecting species in their natural habitats. This allows ecological interactions and evolutionary processes to continue naturally.
Which of the following is an example of in-situ conservation?
- A Zoo
- B Botanical garden collection
- C Wildlife sanctuary
- D Seed bank
Correct answer: Wildlife sanctuary
Wildlife sanctuaries protect organisms in their natural environments. They represent a classic example of in-situ conservation.
Ex-situ conservation is especially useful when:
- A Species populations are stable in the wild
- B Habitats remain undisturbed
- C Species face immediate risk of extinction
- D Natural selection must be enhanced
Correct answer: Species face immediate risk of extinction
Ex-situ conservation is critical when species are at high risk of extinction in the wild. It provides controlled conditions for survival and reproduction.
Which facility is designed specifically for conserving plant genetic diversity?
- A Zoo
- B National park
- C Seed bank
- D Biosphere reserve
Correct answer: Seed bank
Seed banks store seeds under controlled conditions for long-term conservation. They preserve plant genetic diversity for future use.
A major advantage of in-situ conservation is that it:
- A Requires less land area
- B Preserves entire ecosystems
- C Allows complete human control
- D Eliminates competition among species
Correct answer: Preserves entire ecosystems
In-situ conservation protects whole ecosystems, including species interactions. This helps maintain natural evolutionary processes.
Which of the following represents ex-situ conservation of animals?
- A National park
- B Wildlife corridor
- C Zoo
- D Sacred grove
Correct answer: Zoo
Zoos maintain animals outside their natural habitats under controlled conditions. They are a common ex-situ conservation method.
Biosphere reserves differ from national parks because they:
- A Exclude every single form of human activity entirely
- B Focus only on tourism
- C Integrate conservation with sustainable use
- D Are used only for research
Correct answer: Integrate conservation with sustainable use
Biosphere reserves combine conservation with sustainable use of resources. They include core, buffer, and transition zones.
Cryopreservation is most closely associated with:
- A In-situ conservation
- B Ex-situ conservation
- C Habitat restoration
- D Community conservation
Correct answer: Ex-situ conservation
Cryopreservation involves freezing cells or tissues at very low temperatures. It is an advanced method of ex-situ conservation.
Which conservation strategy allows species to continue natural evolution?
- A Zoo breeding programs
- B Seed banks
- C In-situ conservation
- D Cryogenic storage
Correct answer: In-situ conservation
In-situ conservation maintains organisms in natural environments. This allows ongoing natural selection and adaptation.
Sacred groves are considered effective because they:
- A Are officially government-managed commercial timber forests
- B Are protected by cultural and religious beliefs
- C Allow unrestricted exploitation
- D Replace wildlife sanctuaries
Correct answer: Are protected by cultural and religious beliefs
Sacred groves are protected by local communities for cultural or religious reasons. This traditional protection helps conserve biodiversity.
Which of the following is a limitation of ex-situ conservation?
- A High genetic diversity in the population
- B Protection from predators
- C Limited natural selection
- D Controlled breeding
Correct answer: Limited natural selection
Ex-situ conservation often limits exposure to natural environmental pressures. This can reduce the role of natural selection.
Wildlife corridors are important in conservation because they:
- A Increase habitat fragmentation
- B Prevent species migration
- C Connect isolated populations
- D Replace protected areas
Correct answer: Connect isolated populations
Wildlife corridors connect fragmented habitats. They allow gene flow between populations, reducing inbreeding.
Which strategy is best for conserving large populations of organisms?
- A Seed banks
- B Zoos and aquarium enclosures
- C In-situ conservation
- D Cryopreservation
Correct answer: In-situ conservation
In-situ conservation protects large populations within natural habitats. It is more suitable for maintaining population dynamics.
Botanical gardens contribute to conservation mainly by:
- A Protecting entire self-contained natural ecosystems intact
- B Conserving plant species outside natural habitats
- C Restoring wildlife corridors
- D Preventing natural selection
Correct answer: Conserving plant species outside natural habitats
Botanical gardens grow and maintain plant species outside their natural habitats. They are important ex-situ conservation centers.
Which of the following best explains gene banks?
- A Areas for wildlife tourism
- B Natural forests with very high species diversity
- C Facilities storing genetic material
- D Community-managed reserves
Correct answer: Facilities storing genetic material
Gene banks store genetic material such as seeds, pollen, or DNA. They help preserve genetic diversity for future use.
Why is in-situ conservation considered evolutionarily important?
- A It prevents all inherited genetic variation
- B It halts adaptation
- C It maintains natural selective pressures
- D It isolates species permanently
Correct answer: It maintains natural selective pressures
In-situ conservation preserves natural environments where selection pressures act normally. This supports ongoing evolution.
Which method is most suitable for conserving critically endangered species with very low numbers?
- A National parks
- B Wildlife corridors
- C Ex-situ conservation
- D Habitat restoration alone
Correct answer: Ex-situ conservation
Ex-situ conservation provides controlled conditions for breeding endangered species. It helps increase population size safely.
A major challenge in in-situ conservation is:
- A High technological and infrastructure cost
- B Habitat destruction and human pressure
- C Lack of genetic material
- D Artificial breeding difficulties
Correct answer: Habitat destruction and human pressure
In-situ conservation is strongly affected by habitat loss and human activities. These pressures can reduce its effectiveness.
Which conservation approach focuses on preserving evolutionary potential?
- A Cryopreservation
- B Zoo captivity breeding programs
- C In-situ conservation
- D Seed storage
Correct answer: In-situ conservation
In-situ conservation allows populations to adapt naturally over time. This preserves evolutionary potential.
The most effective long-term conservation strategy generally involves:
- A Only ex-situ conservation methods used alone
- B Only in-situ conservation
- C Combining in-situ and ex-situ approaches
- D Artificial habitat creation only
Correct answer: Combining in-situ and ex-situ approaches
Combining in-situ and ex-situ strategies maximizes conservation success. This approach addresses both immediate and long-term threats.
