If the coral and the fish were removed from the ocean ecostyem. How would the ecostyem change?

Removal of coral and fish will cause a great threat to the ocean ecosystem.

Explanation:

Biodiversity of the marine ecosystem will be markedly reduced Marine food web will be affected leading to scarcity of food at each level Mean trophic level of the ecosystem will be affected The ocean chemistry will be changed Habitat destruction of fishes which will affect other aquatic organisms living in the ocean Increases ocean acidification and ocean carbon concentration The animals interdependent on ocean ecosystem for food like some seal, walrus, and sea birds are affected due to scarcity of food through fishes Corals are filter feeders and removing them will lead to eutrophication of coastal waters which in turn leads to algal bloom Algal bloom leads to depletion of the ocean's oxygen level Corals are natural barriers and provide natural protection to shorelines and coastal landforms, removal will endanger the coastlines during floods, hurricanes, etc
