What is Biodiversity? 

Biodiversity



 Organisms gift on this planet show Brobdingnagian structural and purposeful variations.
 They not solely dissent in their external morphology and internal structure, however additionally show variations in their constitution, habitats, habits, life span, etc. 
Such a diversity is exhibited not solely by the people of various teams.
 However additionally by the people of a similar cluster of organisms.
 The variety of life forms seen around U.S.A. is cited because the bio-diversity. It's the biological wealth of the planet.
 It includes the entire vary of mammals, birds, reptiles, amphibians, fishes, insects and alternative invertebrates, plants, fungi and sort of microorganisms like protists, bacteria and viruses.
 Biodiversity is recognized at 3 levels- genetic level, species level and ecosystem level. 

Genetic diversity:

Genetic diversity is outlined as variation in genetic composition of people at intervals or among species. 
Scientists calculated that the variety of living thing organism has genes travel between 100 to a number of a lot. 
The enormity of magnitude of genetic diversity harbored by 13-14 million species is on the far side imagination.
 Genetic variations between the people of a species provides the premise for the variety that's found between 2 species.
 Although studies in genetic diversity don, 't seem to be however terribly widespread and sharply focussed, however, in genetic diversity of some wilds crop relatives and domesticated animals are studied in some details.

 Species diversity:

 Species diversity pertains to the variability of species. So far 1.7 million species of organisms are recorded.
 India' s contribution to the present record stands at seven percent it includes forty-nine thousand species of plants and over eighty-one thousand species of animals.
 As of now, solely seventieth of the world has been surveyed.
 Therefore the flora and fauna already known square measure solely a part of what truly occurs in Bharat.
 The list is being perpetually revised particularly within the case of lower plants and invertebrate animals. 

Ecosystem diversity:

Ecosystem diversity refers to the variety of ecosystems and habitats.
 As we all know there square measure differing kinds of physical options and climatic things over the globe.
 These wide range in things have resulted during a diversity of ecological habitats.
 The different varieties of ecosystems like forests, grasslands, wet lands, coastal and marine ecosystems, and desert ecosystems have terribly giant diversity in them. 

Conclusion- 

Biodiversity is dynamic in the slightest degree the 3 levels.
 The genetic composition of species changes over time in responses to natural and human- elicited choice pressures.
 Incidence and relative abundance of species in ecological communities' amendment as a result of ecological and physical factors and ecosystems respond powerfully to external dynamics and internal pressures.

Name of 100 living organisms in the world

  Name of 100 living organisms in the world There are many living organisms in the world. They are Human, tiger, bear, lion, dog, cat, horse, pig, rat, garden lizards, house lizard, Snell, hippopotamus, mango tree, coconut tree, banyan tree, banana tree, mushrooms, polar bear, yak, cow, goat, sheep, wolf, jacket, fox, tortoise, cobra, anaconda, crocodile, pegion, peacock, hen, parrot, bacteria, algae, ant, spider etc. Basis characteristics of living organism Following  basic characteristics of living organisms  distinguish them from non-living. These are the basic  19 characters of living organisms 1. Individuality:  Every  organism  exists as a single unit and has its own individuality. It can't be separated into completely different components for its survival.  2. Form and size:  Every  organism  incorporates a definite form and size. A non-living object will have any form.  3. Chemical organization:   Organisms  a...

Stem

The study of varied external options of the plants is understood as a plant morphology.  The angiosperm is characterized by presence of roots, stems, leaves, flowers, and fruits.  These are the most characteristics of angiosperms.  The stem is the ascending part of the axis bearing branches, leaves, flower and fruits.  It develops from the down feather of the embryo of a germinating seed.  The stem bears nodes and internodes.  The regions of the stem wherever leaves are born are known as nodes, whereas, internodes are the parts between 2 nodes.  The main operate of the stem is spreading out branches, bearing leaves, flowers, and fruits.  Modification of stem  1. Rhizome-  Rhizome are non-inexperienced with distinct nodes and internodes.  These are brown in color.  Example- Ginger  2. Bulb- The bulb might tunicated.  A sheath of dry membranes scale leaves protected the chordate bulb.  Example- Oni...
