Abstract

Climate change is change in the annual weather pattern of an area due to anthropogenic activities. Climate change is a medium which reshapes the way of transferring contamination through the global environment, it has changed the chemistry of oceans. Freshwater bodies such as rivers, canals, lakes and ponds and affected the function and structure of food webs, and feeding ecology of marine biota. Phytoplankton is the base component of aquatic food webs as producers so a little bit Sea water temperature fluctuations affect all the occurring biological and ecological processes and cause the destruction of trophic level in marine ecosystem. While in terrestrial food webs producers are most essential element. But due to rapid consumption of forest which may leads to deforestation become the reason of disruption in many food webs. Also many anthropogenic activities such as hunting invasive species is also another factor of disturbance in any food web.
