Introduction
All the organisms living or inhabiting in the bottom regions of the aquatic environments are termed benthos.These benthos/benthic organisms live in a variety of bottom environments of the aquatic ecosystems and are as diverse as the plankton.These bottom living organisms have direct contact with the substrate, which limits the distribution of these organisms.The factors such as the composition, size of the particles, its firmness or resistance to penetration, its lability and the food they contain, are all known to have major influence on the distribution of organisms./b> |
