If we explore new areas and even old ones, new organisms are continuously being added. The living world includes all the living organisms, such as microorganisms, plants, animals and humans. According to a survey, the number of species that are known and described are between 1.7-1.8 million. It uses evidences from all the areas of biology like morphology, anatomy, biochemistry, cell biology, physiology, genetics, evolution, etc. Therefore, consciousness can also said to be a defining property of living organisms. In multi cellular organisms in particular, growth occur by cell division or increase in number of cells. NB : There are certain examples in which mass is decreased during growth e.g. Hindi, Marathi, \u0026 Sanskrit.

Thus, classification is the process by which organisms are grouped into categories based on some easily observable characters. We have discussed some important and defining characteristics of living things. (iii) A new taxon can be framed if the organism is different from the existing taxa. However, in human beings, it is more difficult to define living state, e.g., Patients lying in coma supported by machines that replace heart and lungs, are brain-dead with no self-consciousness.

There are about 1.7 to 1.8 million species known. Class-Mammalia has other orders also. Ans :- Life is the name of external manifestation of chemical activities of protoplasm. Metabolism is an another characteristic and defining feature of all living things. Living organisms, whether unicellular or multi-cellular, grow due to cell division. All this information is used in classification of an organism and is also stored along with the specimens. The organisms live in various habitats like forests, mountains, deserts, oceans, freshwater bodies, hot springs, polar regions and almost every place of the earth.
