Question 14 Marks
Read the following and answer any four questions from (i) to (v) given below:
Ginkgo tree has been saved from extinction by selective breeding followed by channeling into trade of nature lovers. This is an ex-situ conservation, where endangered species are protected from all adverse factors. Offspring produced in captive breeding are released in natural habitat for acclimatisation.

- Assertion is true but reason is false.
- Both assertion and reason are false.
Answer
Wetlands are called Ramsar sites. They are low lying marshy areas which get filled up during rains due to run off and overflow from other water bodies.
ln case of in situ conservation procedure, species population recovers in natural environment. ln ex situ conservation, offspring produced in captive breeding are released in natural habitat for acclimatisation.
