Classification of Living Organisms

Nature is formed by nonliving and living organisms. One who has life and performs biological
processes and manifests to enviroment is called living organism. Living organism possess certain characters
like-reproduction, growth, development, reaction with environment adaptation and death. Besides these
it has characteristics like metabalism, entropy, efficiency to maintain heredity. It produces new generation
through reproduction. Energy is reguired during metabolism. Growth is a out put of metabolism. Quantity
increases due to growth. Tissues and organs are formed due to differentiation and organigenesis occurs
during development living organism shows efficiency of manifestations of feeling towards environment.
It obtains adaptations to sustain in an environment and creates variations for adaptation. New species is
created due to variation, hence biodiversity forms. It has efficiency to maintain heredity before its death.
There is an aggregation of different layers in living organisms. Membranes are formed of large
molecules and molecules are formed from atoms. Cell is formed by membranus organelles. Tissue is
constituted by group of cells which are present in organ and organ system. Body is composed by such
organ systems. Such living organism is known as species. Population is structured by group of species.
Such combined population of a same habitat form a biotic community. By interaction between biotic
community and environment is constituted an ecosystem. By composition of ecosystems biosphere is
The study of living organisms can be done by nomenclature and identification characters. Living
organisms are classified in to groups. Meaningfully called classification which has species, genus, order,
family, class, phylum and kingdom. There are certain rules and regulations. Many scientist’s have
contributed in this field. There are various sources for study.
