Which one of the following is not included under in situ conservation?
- Sanctuary
- Botanical garden
- Biosphere reserve
- National park
The Correct Option is B
Solution and Explanation
In situ conservation refers to the conservation of species within their natural habitats. It includes protected areas like sanctuaries, biosphere reserves, and national parks, where species are conserved in their native ecosystems. Botanical gardens, on the other hand, are examples of ex situ conservation, where plants are grown and conserved outside their natural habitats, often in controlled environments like gardens or greenhouses.
So, the correct option is (B): Botanical garden

- The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant \(K_1\) and \(K_2\) with thickness \(d/2\) and \(d/2\) respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If \(K_1 = 1.25 K_2\), the value of \(K_2\) is :

Biodiversity and Conservation
The term ‘biodiversity’ is derived from the two words- ‘bios' which means life and ‘diversity’ i.e, differentiation or variation. Edward Wilson, the sociobiologist was the first to popularise the term ‘biodiversity’ in the year 1992. The term implies the occurrence of various plants and animals along with their variants such as biotypes, ecotypes and genes on earth. In our biosphere, the immense diversity or heterogeneity remains not only at the species level but also, at every level of biological organization that ranges from macromolecules in the cells to biomes.
Biodiversity and Conservation is a topic covered under the fifteenth chapter and Unit 5 of NCERT class 12 biology.
