Outline at least 3 ecological roles of marine flowering plants
What will be an ideal response?
Marine flowering plants play a number of ecological roles in their environments. They trap and stabilize sediments, which leads to the building up of coastlines; they filter runoff from land, absorbing harmful chemicals and nutrients, thereby preventing eutrophication of nearby waters; they are an important source for detritus, which supplies food to nearby communities; they are direct sources of food for many grazers; and they are an important shelter for many marine animals.
