Explain why the presence of large numbers of algae results in a fall in the amount of oxygen dissolved in the water. (iii) There are very few submerged water plants at Site B. Use (iii) the graphs to suggest how placing a speed limit on boats might allow submerged water plants to become re-established at Site B.arrow_forward
