classification of matter

  NEED FOR CLASsIFICATION lhe number ot living beings, the plants and animals is enormous. Further many new forms are aiscovered and added every year. Plants, animals or microorganisms have great diversity in their form, structure and mode of ire. lo find an organism of known characters from the vast number of organisms is almost imposible. They need to be divided into groups or subgroups. Arranging and grouping the organisms in a definite principle, makes the study of living organisms easy. Just by selecting a few representatives from each group, a broad idea of lite in this earth can be achieved. Therefore, a good system of classification is must for their identification, study and bringing out relationships amongst themselves. 6 ch So needs for classification are . It is not possible to study every organism at a time. The study of one Or two organisms of a group give sufficient information about the essential features of the group. 2.

what is biodiversity

  Concept of biodiversity  The term biodiversity was first proposed by Walter Rosen (1985).  The diversity of organisms is very small, showing extreme diversity.  Currently, the number of species of all organisms known and described or   rth is between 1.7 and 1.8 million, which is less than 15% of the actual number.  It is predicted that the total number of species ranges from 5 to 50 million.  Most of them are believed to occur in tropical rain forests and underwater coral reefs in tropical waters.  The most exciting problem with more than 70% of biological species is animals, while plants account for only 22%.  In animals, ir   e is the largest in number (about 70%). It was estimated that there were 7 out of 10 in the past, and it is currently estimated that there are 8 in this population.  In addition, knowledge about protists, archaea, bacteria, and viruses is very fragmented.  Undeveloped tropical forests and coral reefs ...
