Development of Food Web Model Including Microbial loop and Impact on Food web dynamics by Bacteria

Abstract

 The food web model of water mass is urged to be able to express change of the food web dynamic which changes with trophic levels. Moreover, it is thought that bacteria which are main decomposer affect the whole food web in respect of nutrient reproduction.The purpose of this study is to construct a Food web model based on verification by an observation phenomenon and to show the influence which bacteria have on a food web dynamic using a model.
 It was shown that the built model can reproduce the biomass and its composition, energy flux and phosphorus regeneration by the different trophic level. Bacteria changed phosphorus regeneration and affected the Total biomass. Moreover, the microbial food chain which makes bacteria a starting point played the important role in the field of the predation pressure to a primary producer, and the energy transfer to a higher level predator, and has contributed to suitable modeling of a food web dynamic state. It was shown that the impact which makes bacteria a starting point is what affects the whole food web.
