Transcript

  • 1. This thing is made by Mr.Tanishq Rahuja of class 5thb,thankyou.BIODIVERSI
  • 2. What does the word biodiversitymeans? Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species, and of ecosystems.
  • 3. Indias biodiversity. India displays significant biodiversity. One of eighteen megadiverse countries. It has about 27% of earths bird species and it is home to 7.6% of all mammalian, 12.6% of all avian, 6.2% of all reptilian, 4.4% of all amphibian, 11.7% of all fish, and 6.0% of all flowering plant species along with 1.2 Billion people in just over 3 million km2
  • 4. New species New species are regularly discovered (on average between 5– 10,000 new species each year, most of them insects) and many, though discovered, are not yet classified (estimates are that nearly 90% of all arthropods are not yet classified).[34] Most of the terrestrial diversity is found in tropical forests.
  • 5. Human needs. Although about 80 percent of humans food supply comes from just 20 kinds of plants,[citation needed] humans use at least 40,000 species to live. Many people depend on these species for food, shelter, and clothing] Earths surviving biodiversity provides resources for increasing the range of food and other products suitable for human use, although the present extinction rate shrinks that potential
  • 6. Where is biodiverssity. Biodiversity is essentially everywhere, ubiquitous on Earth’s surface and in every drop of its bodies of water. The virtual omnipresence of life on Earth is seldom appreciated because most organisms are small (<5 centimeters); their presence is sparse, ephemeral, or cryptic, or, in the case of microbes, they are invisible to the unaided human eye
  • 7. Ecosystem services. Biodiversity supports many ecosystem services that are often not readily visible. It plays a part in regulating the chemistry of our atmosphere and water supply. Biodiversity is directly involved in water purification, recycling nutrients and providing fertile soils. Experiments with controlled environments have shown that humans cannot easily build ecosystems to support human needs; for example insect pollination cannot be mimicked, and that activity alone represents tens of billions of dollars in ecosystem services per year to humankind
  • 8. Picture gallery
  • 9.  On 7/11/12 we visited the charbagh railway station where an 16coached train was decorated in a way that shows what is biodiversity. That is the pic of their team leader not ours
