Read the passage carefully and answer the questions based on the passage:
Species diversity on earth is not uniformly distributed. It is generally highest in the tropics and decreases towards the poles. Earth’s fossil history reveals the incidences of mass extinctions in the past. Earth’s rich biodiversity is vital for the very survival of mankind. It is believed that communities with high diversity tend to be less variable and more productive. The reasons of conserving biodiversity are narrowly utilitarian, broadly utilitarian and ethical. Biodiversity conservation may be in situ as well as ex-situ.
Which of the following is not included in in-situ conservation?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Zoological park
The passage says that biodiversity conservation may be in situ or ex situ. In situ conservation protects species in their own natural habitat, so the whole ecosystem is saved. Ex situ conservation takes them out and keeps them in special places.
Option (1) Zoological park — Not in situ conservation. In a zoo the animals are taken out of their natural habitat, so it is ex situ conservation.
Option (2) National park — In situ conservation. A national park protects the animals and plants where they naturally live.
Option (3) Wild life sanctuary — In situ conservation. A sanctuary is a protected part of the natural habitat.
Option (4) Biosphere reserves — In situ conservation. India’s biosphere reserves protect whole ecosystems on site.
