Thank you for the lesson Ms. Prakash. Your efforts are highly appreciated. I have a doubt here if you could kindly guide me. A farmer sells his wheat to a biscuit mfg. company. The biscuit mfg. company produces biscuits out of it. Now, what will we consider for calculating the GDP, both the biscuits mfd. by the company and the wheat sold by the farmer or just the biscuit mfd. by the company? Please give reason for your answer. Thank you.

just the value of it already includes the cost of wheat

So then we don't consider the total wheat (or any food grain for that matter) for the calculation of GDP. Do we?

no ,bcoz GDP is value of all final goods and services produce within a country here is imp.( final goods n service )

I too have the same doubt. "Value of final goods of each sector.." is included in calculation of GDP. Value of wheat, which is the final product of Primary sector, is not included?

  4. Indian biodiversity diverse landscape India is one of the recognized mega diverse countries of the world. In terms of species richness, India ranks seventh in mammals, ninth in birds and fifth in reptiles. In terms of endemism of vertebrate groups, India's position is tenth in birds with 69 species, fifth in reptiles with 156 species and seventh in amphibians with 110 species. India's share of crops is 44% as compared to the world average of 11 %. India also has 23.39 percent of its geographical area under forest and tree cover. Of the 34 globally identified biodiversity hotspots, India harbours two hotspots, i.e., Eastern Himalayas, Western Ghats and Sri Lanka .

  5. INDIA REPRESENTS: a) Two 'Realms b) Five Biomes c) Ten Bio-geographic Zones d) Twenty five Bio-geographic provinces Realms: Biogeographic realms are arge of the 8 biogeographic realms spatial regionswithin which Nearctic ecosystems share a broadly similar biota.Realm is a continent or sub continent sized area with unifying features of geography and fauna & flora. The Indian region is Afrotropic Indomalaya Australasia Neotropic composed of two realms.They are: cni and Antarctic ecozones

  6. 1) the Himalayan region represented by Palearctic Realm and 2) the rest of the sub-continent represented by Malayan Realm Biomes of India: . The term biome means the main groups of plants and animals living in areas of certain climate patterns. It includes the way in which animals, vegetation and soil interact together. The plants and animals of that area have adapted to that environment. The five biomes of India are: 1) Tropical Humid Forests 2) Tropical Dry or Deciduous Forests (including Monsoon Forests) 3) Warm deserts and semi-deserts 4) Coniferous forests and 5) Alpine meadows.


  8. Biogeography deals with the geographical distribution of plants and animals. There are 10 biogeographic zones which are distinguished clearly in India. They are as follows-- 1) Trans-Himalayas. An extension of the Tibetan plateau, harboring high- altitude cold desert in Laddakh (J&K) and Lahaul Spiti (H.P) comprising 57 % of the country's landmass. 2) Himalayas. The entire mountain chain running from north-western to northeastern India, comprising a diverse range of biotic provinces and biomes, 7.2 % of the country's landmass. 3) Desert. The extremely arid area west of the Aravalli hill range, comprising both the salty desert of Gujarat and the sand desert of Rajasthan. 6.9% of the country's landmass. 4) Semi-arid. The zone between the desert and the Deccan plateau, including the Aravalli hill range 15.6 % of the country's landmass.

  9. 5) Western ghats. The hill ranges and plains running along the western coastline, south of the Tapti river, covering an extremely diverse range of biotic provinces and biomes. 5.8% of the country's landmass. 6) Deccan peninsula. The largest of the zones, covering much of the southern and southcentral plateau with a predominantly deciduous vegetation. 4.3 % of the country's landmass. 7) Gangetic plain. Defined by the Ganges river system, these plains are relatively homogenous. 11 % of the country's landmass. 8) North-east India. The plains and non-Himalayan hill ranges of north eastern India, with a wide variation of vegetation. 5.2% of the country's landmass. 9) Islands. The Andaman and Nicobar Islands in the Bay of Bengal, with a highly diverse set of biomes. 0.03% of the country's landmass

  10. 10) Coasts. A large coastline distributed both to the west and east, with distinct differences between the two; Lakshadeep islands are included in this with the percent area being negligible Biogeography is divided into branches: 1. Phyto-geography (plant geography) deals with origin, distribution and environmental interrelationships of plants. Zoogeography deals with the migration and distribution of animals. 2. Bio-geographic provinces. Bio-geographic Province is a eco systematic or biotic subdivision of realms. India is divided into 25 bio geographic zones Vertebrates It comprise all species of animals within the subphylum Vertebrata.

  12. Annelids Annelids have bodies that are divided into segments. They have very well-developed internal organs. Found almost anywhere in the world. " They don't have any limbs. E.g: earthworms, leeches, roundworms, etc. Mollusks Most mollusks have a soft, skin-like organ covered with a hard outside shell. Some mollusks live on land, such as the snail and slug. Other mollusks live in water, such as the oyster, mussel, clam, squid ano RS AS octopus. Echinoderms Echinoderms are marine animals that live in the ocean
