organism within the ecosystem form the two basic concepts - habitat and niche which are useful in describing the ecologic relations of organisms.43 In dealing with the ecosystem and adaptation of organisms in Jaina Biology it is revealed that the biogeorgraphic regions of the world are regions composed of a whole continent (dvipa ) or a large part of it (i. e. sthalacarast hānas)44 and characterized by certain unique animals and plants.45 Within these biogeorgraphic divisions and arising as a result of complex interactions of climate, other physical factors and biotic factors are large, distinct, easily differentiated community units, called biomes in modern Biology. 46
It is suggestive from the study of the classification of plants47 into bacteria, algae, fungi, herbs, shrubs, creepers, grasses and trees in Jaina Biology that in each biome the kind of climax vegetation is uniform, but the particular species of plant may vary in different parts of biome. The kind of climax vegetation depends upon the physical environment and the two together determine the kind of animals present.48
According to modern Biology, “The definition of biome includes not only the actual climax community of a region, but also the several intermediate communities that precede she climax community 49”. Aquatic Life Zones (Jalacarasthānas)
Aquatic Life Zones may be divided into Marine Life zones 50 and Fresh Water Life zones for the convenience of study of biomes in these habitats.51
