It has been found that the rainforests are accountable for about one-third, that is, 28 percent of the oxygen of the Earth, however, the majority of the oxygen, that is, about 70 percent in the atmosphere is generated by the marine plants. The left-over two percent of the oxygen comes from other sources.
The majority of the oxygen comes from the tiny plants in the ocean known as phytoplankton, which lives near the surface of the water and drifts with the currents. Similarly to plants, they perform the process of photosynthesis, that is, they utilize carbon dioxide and sunlight to prepare food, oxygen is the by-product of photosynthesis.
However, the concentration of the dissolved oxygen, which the water can hold relies on the salinity and temperature of the water. The cold water can withhold more oxygen in comparison to warm water and fresh water can hold more oxygen in comparison to salt water. So, the warmer and saltier the water is, the less will be the oxygen dissolved in it.

Answer:
Relative age only tells us the order in which events occurred, from the earliest to the most recent. Knowing the actual date of an event allows us to say exactly how old something is or how long ago it actually took place.

Answer:
The first and 2nd pictures basically capture what they look like.
The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
