Question

Which is an example of ex situ conservation?

• A. Sacred grove
• B. Biosphere reserve
• C. National park
• D. Botanical garden

Hint:

Remember: \[ \boxed{ \begin{aligned} \textbf{In situ} &\rightarrow \text{National park, Wildlife sanctuary, Biosphere reserve, Sacred grove}\\ \textbf{Ex situ} &\rightarrow \text{Botanical garden, Zoo, Seed bank, Gene bank} \end{aligned} } \] Ex situ conservation protects organisms outside their natural habitat.

Answer 1

The Correct Option is D

Concept: Conservation of biodiversity is of two types: \[ \boxed{ \begin{aligned} \textbf{In situ conservation} &\rightarrow \text{Conservation in the natural habitat}\\ \textbf{Ex situ conservation} &\rightarrow \text{Conservation outside the natural habitat} \end{aligned} } \] Ex situ conservation protects endangered plants and animals by maintaining them in controlled environments. Examples include botanical gardens, zoological parks, seed banks and gene banks.

Step 1: Understand ex situ conservation.
In ex situ conservation, organisms are conserved outside their natural habitats under human supervision. Examples are \[ \boxed{ \begin{aligned} &\text{Botanical gardens}\\ &\text{Zoological parks}\\ &\text{Seed banks}\\ &\text{Gene banks} \end{aligned} } \]

Step 2: Analyse the given options.

• Sacred grove → In situ conservation.

• Biosphere reserve → In situ conservation.

• National park → In situ conservation.

• Botanical garden → Ex situ conservation.
Thus, only the botanical garden is an example of ex situ conservation.

Step 3: Choose the correct option.
Therefore, \[ \boxed{\textbf{Option (D)}} \] is the correct answer.
