Practice question

Indian Desert biogeographic zone includes Thar Desert covering western Rajasthan, northern Gujarat Kutch Rann, adjoining Haryana Punjab with sand dunes, salty pans, rocky outcrops, and thorn scrub vegetation of Acacia, Prosopis juliflora, Calotropis. Kutch segment includes saline marshes Great and Little Rann, Banni grasslands, and mangroves. Both Thar and Kutch constitute single biogeographic unit due to similar arid climate, edaphic conditions, and faunal assemblage including desert fox, caracal, bustards, spiny-tailed lizard, representing extreme xerophytic adaptations. Clarity on this principle prevents confusion between in-situ and ex-situ methods often interchanged in examination options.
