Question Discussion & Solution

​The correct answer is Sirohi.

• The district of Rajasthan, where the tropical dry deciduous forests are not found in Sirohi.

Key Points

• Biodiversity of Rajasthan:
  • Though a large percentage of the total area is desert and even though there is little forest cover, Rajasthan has rich and varied flora and fauna.
  • The natural vegetation is classed as Northern Desert Thorn Forest (Champion 1936).
  • These occur in small clumps scattered in more or less open forms.
  • The density and size of patches increase from west to east following the increase in rainfall.
  • The Northwestern thorn scrub forests lie in a band around the Thar Desert, between the desert and the Aravallis.
  • The Aravalli and the south-eastern region is home to the dry deciduous forests, with tropical dry broadleaf forests that include teak, Acacia, and other trees. Hence Sirohi is the correct answer.
  • The hilly ‘Vagad’ region lies in southernmost Rajasthan.
  • Vagad is the wettest region in Rajasthan, and the most heavily forested.
  • North of ‘Vagad’ lies the Mewar region, home to the cities of Udaipur and Chittaurgarh.
  • All these regions have varied flora and fauna distinct to the region.

Additional Information 

• Plant Biodiversity:
  •  Red data Species - 02
  • Orchids - 14
  • Terrestrial - 08
  • Epiphytic - 06
  • Parasitic Species -10
  • Carnivorous Species - 05
  • Endemic Species -19
  • Medicinal Plant Species -157+ 

The code for ‘IRONIC’ would be ‘#!?@#&’.

Food chain: 

• A food chain shows the feeding relationship between different organisms in a particular environment and/or habitat.
• A food chain shows how energy is passed from the sun to producers, from producers to consumers, and from consumers to decomposes such as fungi.
• They also show how animals depend on other organisms for food.
• A simplified food web illustrating a three-trophic food chain (producers-herbivores-carnivores) linked to decomposers.

Key Points

Food Web: 

• A food web is similar to a food chain, but the food web is significantly larger.
• Occasionally, a single organism is eaten by a large number of predators, or it consumes a number of other species.
• As a result, several trophic levels become intertwined, and the food chain fails to accurately depict the flow of resources.
• The food chains are very simple and hence, do not exist in reality, 
• Rather, an interconnection of many food chains is seen in nature or in our ecosystem that forms a food web.
• The energy flow is multidirectional.
• In a food web, one organism takes place at different trophic levels in different food chains (which combine to form a complex food web).
• It gives greater stability to the ecosystem.

​Thus, a group of interconnected food chains is called a food web.

Additional Information

Pyramid of Biomass:

• A biomass pyramid is a diagram that compares the biomass of different trophic levels within an ecosystem.
• It shows the mass of producers that are needed to support primary consumers, the mass of primary consumers required to support secondary consumers, and so on.

The correct answer is Accumulator.

Key Points

• An accumulator is a type of register present in a CPU (Central Processing Unit).
• It works as a temporary storage location that keeps an intermediate value in logical and mathematical calculations.
• Intermediate results of execution are progressively stored in the accumulator, replacing the previous value.

Additional Information

• An IR (Instruction Register) saves machine instruction that is currently under execution. It is a register that sits at the top of the memory hierarchy. A variety of registers fulfills different operations in a central processing unit (CPU) – the function of the IR is to keep that currently stacked instruction for use.
• A PC (program counter) is a CPU register that has the address stored for the next instruction to be processed from memory. It is a digital counter required for quicker execution of tasks as well as to keep track of the current execution point. 
• The MAR (Memory Address Register) is the register in the control unit that holds the address of a register to receive or store from or to the storage. The Memory Address Register is half of an interaction between a microprogram and storage.

The correct answer is In 1959.

• In 1959 the Rajasthan Zamindari and Biswedari Abolition Act passed.

Key Points

• Rajasthan Zamindari and Biswedari Abolition Act
  • This Act may be called the Rajasthan Zamindari and Biswedari Abolition Act, 1959.
  • It extends to the whole of the State of Rajasthan.
  • In this Act, unless the subject or context otherwise requires,-
    • "Biswedar" has the meaning assigned to it by clause (5) of Section 5 of the Rajasthan Tenancy Act, 1955 (Rajasthan Act 3 of 1955).
  • "estate" means land, or right, title or interest in land, held by a Biswedar or a Zamindar;
  • "settled" has the meaning assigned to it by clause (n) of Section 2 of the Rajasthan Land Reforms and Resumption of Jagirs Act, 1952 (Rajasthan Act 6 of 1952);
  • "Zamindar" has the meaning assigned to it by clause (46) of Section 5 of the Rajasthan Tenancy Act, 1955 (Rajasthan Act 3 of 1955) and includes a malik (landowner) in the Gang Canal area.

Additional Information

• Significance of the Rajasthan Zamindari and Biswedari Abolition Act
  • ​As soon as after the commencement of this Act, the State Government by notification in the Official Gazette ordered for the abolition and acquisition of Zamindari and Biswedari estates, or any class of such estates, in the State, or in any area thereof specified in the notification, and for their vesting in the State Government.
