In-situ conservation refers to the protection of species within their natural ecosystems. This approach is exemplified by protected areas such as biosphere reserves, national parks, and wildlife sanctuaries.
In contrast, ex-situ conservation involves relocating endangered species from their native environments to controlled facilities where they receive specialized care and protection. For instance, botanical gardens cultivate plants outside their natural habitats, making them a prime example of ex-situ conservation efforts.
In-situ conservation refers to the conservation of species in their natural habitats, where they are protected from environmental threats. This includes:
National Parks, Sanctuaries, and Biosphere Reserves. These are areas where species are preserved in their natural environments.
However, Botanical Gardens are an example of ex-situ conservation, which is conservation outside the natural habitat. In botanical gardens, plants are grown in controlled environments for research, education, and preservation purposes.

A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
