Answer:
The water cycle involves the circulation of water on, above and below the surface of the earth. Acid rain enters the water cycle through both wet and dry depositions.

The reason why animals need continuous supply of oxygen is to survive. Almost all of the animals rely on the oxygen in order to be able to survive and function properly.
The oxygen is what enables the respiration, and the respiration is what allows for the cells to be alive and be able to function. Without constant oxygen supply, the cells will not be able to function, thus they will die, which will cause the whole organism to die.
Also, the oxygen is a gas that is used for the burning of glucose into fuel. This basically means that the oxygen is the final detail that enables the organism to obtain nutrients. If the oxygen is not present, than the organism will do everything to create glucose and it will manage to, but it will not be able to turn into a fuel for itself, thus it will not be usable.

Answer:
The cause of phytoplankton blooms has traditionally been attributed to seasonal changes in ‘bottom-up’ environmental factors controlling phytoplankton division rates, such as nutrients and light 3,4,5,6,7. However, seasonal changes in phytoplankton biomass (P) represented by the biomass-specific net rate of change (r) always reflect the interplay between two dominant terms, the phytoplankton division rate (μ) and the sum of all loss (l) rates (e.g., grazing, viruses, sinking):
Explanation:
The photosynthetic production of organic carbon by marine phytoplankton plays a key role in regulating atmospheric carbon dioxide (CO2) levels, such that without this biological uptake it is estimated that present day atmospheric CO2 concentrations would be 200 ppm (50%) higher1. Phytoplankton blooms in the temperate and polar oceans play a disproportionally large role in ocean CO2 uptake, as well as being critical ecological events to which the migration patterns of marine animals, ranging from zooplankton to whales, have evolved2.
