The correct answer is '<span>Oxygen is used up as algae is decomposed, reducing the amount available to other organisms.</span>' The additional nutrients in the water will result in an algal bloom. These algae will result in drastic oxygen fluctuation, from oxygen rich conditions during the day as algae photosynthesize, to anoxic conditions during the night when the algae respire. However, the algal bloom will eventually deplete the available nutrients, resulting in a vast algal die off. The decomposing algae result in anoxic conditions, and the effects are sometimes very obvious, with fish gasping for breath and dying.
No, Humans take evolution through selective breeding and genetically modified organisms.
Weathering because it's "wearing" down something to make sediment
Heat water using the sun during the day, and use it during the cold night.
Use a solar panel to charge batteries during the day, and use the power at night.
