Abstract

Abstract
 
The effect of living organisms in forming the geomorphology of the study area and the appearance of their signs in the rocks depends on the environmental needs and sensitivity of the organism, as well as interaction with other organisms and competition for food and place. Where many organisms destroy rocks by different means in the tidal range, where this zone is considered the most affected by many organisms, as it appears that bio-erosion is the most influential in the study area .
 
     In the Study area there are many forms of biogeographic surfaces that result from biological disturbances, and biological disturbance is defined as the destabilization of the surface caused by the various biological activities of the macrozoobenthos, whether it is the destabilization of a surface soil layer on land or the seabed, such as slits resulting from movement or burrows in search of food or The shelter. Which would modify the patterns of sediment layers and work to invert the mosses between the deep and the surface soil, and the turbulence of the surface and the amount of this turbulence are due to the properties of this surface.
