Which of the following statements about ex‑situ conservation is incorrect?

hard MCQ 4 marks Class 12 · Biology · Biodiversity and Conservation
  1. a) Ex situ conservation ensures immediate protection of species in their natural habitat.
  2. b) It allows controlled breeding to increase population size.
  3. c) Facilities like zoos provide opportunities for research on reproductive biology.
  4. d) It can reduce the risk of extinction by maintaining captive populations.
Answer
a) Ex situ conservation ensures immediate protection of species in their natural habitat.

The correct answer is a) Ex situ conservation ensures immediate protection of species in their natural habitat. — Step 6: Since only option a is false, the correct answer is option a.

Step-by-step solution

  1. Step 1: Understand what ex‑situ conservation actually does – it involves protecting species outside their natural environment, e.g., in zoos, botanical gardens or seed banks.
  2. Step 2: Evaluate option a – it claims ex‑situ provides immediate protection in natural habitats. This is false because the protection occurs outside the habitat.
  3. Step 3: Evaluate option b – controlled breeding to increase population size is a primary benefit of ex‑situ. This statement is correct.
  4. Step 4: Evaluate option c – zoos and research centres provide opportunities for scientific research on reproduction, disease etc. Correct statement.
  5. Step 5: Evaluate option d – ex‑situ facilities maintain captive populations that reduce extinction risk. Correct statement.
  6. Step 6: Since only option a is false, the correct answer is option a.
Common mistake: Confusing ex‑situ with in‑situ conservation benefits

Concept tested: Distinguishing ex‑situ vs in‑situ conservation
