is used to refer Top Biodiversity Countries.This type Country can get national or international award for Biodiversity conservation in nations.

4) State two reasons for Destroying Biodiversity.
=>i) Killing / cutting Forests continuously.
ii) Globalization is a victim of Destroying Biodiversity.

5)State Full Name:-
i)WWF =>World Wide Fund For Nature
ii)CITES=Conservation On International Trade In Endangered Species of wild Fauna And Flora.
iii)ICUN=>International Union For Conservation Of Nature.

6)What Is Mutation?
=>When A DNA gene changes in a such way as to alter the genetic message carried bu that gene,is calls Mutation.

7)State The Feature of living Being.
=>Some Features of Living being are:-
i)Growth......(ii)Metabolism....(iii) Sensitivity or irritability...(iv)Reproduction etc.

8)What Is Cryopreservation?
=>Cryopreservation or cryoconservation is a process where organelles, cells, tissues, extracellular matrix, organs or any other biological constructs susceptible to damage caused by unregulated chemical.

9)State the Conditions for become a Biodiversity Hotspot.
=>From The Rule Of 'Conservation International'(CI) The Main Two Conditions Are:-
i)In A Hotspot there should be maximum 1500 endemic Species.
ii)In Any Hotspot, there should be 70% of Aborigines is Defunct.

10)Who Used The Word 'Biodiversity' First?
=>W.G. Rosen

11)What Is In-Situ Conservation?
=>In-situ conservation is the on-siteconservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of Teagan species.

12)What Is Ex-situ Conservation?
=>Ex situ conservation is theconservation and maintenance of samples of living organisms outside their natural habitat, in the form of whole plants, seed, pollen, vegetative propagules, tissue or cell cultures.

13) Examples Of Ex-situ Conservation &In-Situ Conservation.
=>In-Situ Conservation:-National Parks, Biosphere Reserve etc.
=>Botanical Garden, Cryopreservation etc.

14)What is Endemic Species?
=>Endemism is the ecological state of aspecies being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemicto it if they are also found elsewhere.

15)What Is Biosphere Reserve?
=>Biosphere Reserve is a scientific basis for the improvement of relationships between people and their environments.

16)State Difference Between National Park & Wildlife Sanctuary.
-----National Park-----|-Biosphere Reserve
=>______________|_______________
i)India Has 103............|i) India Has 537

Answer 2

Heya !!!

Here's your answer !!

➡Characteristics of Living Organisms:

Growth, reproduction, metabolism, cellular organisation, consciousness (ability to sense environment), self-replicating and self regulation.
1. Reproduction and growth are NOT defining properties.
2. Metabolism, cellular organisation and consciousness are defining properties.


➡Biodiversity

Biodiversity : Term used to refer to the number of varieties of plant and animals on earth.


➡Need for classification:

To organise the vast number of plants and animals into categories that could be named, remembered, studied and understood.


➡Rules for Nomenclature :

->Latinized names are used, written in italics
->First word represents the genus, second word is species name.
->Printed in italics; if handwritten then underline separately.
->First word starts with capital letter while species name written in small letter.


➡ICBN :

International Code of Botanical Nomenclature (for giving scientific name to plants.)


➡ICZN:

International Code of Zoological Nomenclature (for giving scientific name to animals.)


➡Taxonomy:

Study of principles and procedures of classification.


➡Binomial Nomenclature:

Given by Carolus Linnaeus. Each scientific name has two components - Generic name + Specific epithet.


➡Systematics :

It deals with classification of organisms based on their diversities and relationships among them. Term was proposed by Carlous Linnaeus who wrote ‘Systema Naturae’.


➡Taxonomic Hierarchy:

Arrangement of various steps (categories or taxa or ranks) of classification.
Species -> Genus ->Family -> Order -> Class -> Phylum (for animals) / Division (for plants) Kingdom ->

➡Species:

All the members that can interbreed among themselves and can produce fertile offsprings are the members of same species. This is the biological concept of species proposed by Mayr.


➡Three Domains of Life :

Proposed by Carl Woese in 1990 who also proposed the six kingdom classification for living organisms. The three Domains are Archaea, Bacteria and Eukarya.


➡Herbarium:
Storehouse of dried, pressed and preserved plant specimen on sheets.


➡Botanical Garden:

Collection of living plants for reference.


➡Taxonomical aids :

Zoological Park (Places where wild animals are kept in protected environment.)
->Keys (Used for identification of plant and animals on the basis of similarities and dissimilarities.)
->Fauna: (Index to animal species found in a particular area)
->Flora (Index to plant species found in a particular area.)
->Manuals (Provide information for identification of name of species in an area.)
->Monograph (Contain information on one taxon.)
