<h2>Removal of coral and fish will cause a great threat to the ocean ecosystem
.</h2>
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
