Why is the concentration of oxygen higher near the surface than on the bottom of the ocean?
because the oxygen rises and floats so it will always stay above and think about it if there was oxygen on bottom layers we would be able to breathe and live under water thanks for searching
hey call me!!!!!!!

Also there is more sunlight in the surface layers, and therefore more plants, as they need the sunlight to photosynthesise. In the process of photosynthesis, carbon dioxide and water combine to form oxygen and carbohyadrates. So basically there is more oxygen in these layers as there is more plants to release oxygen there.
What else can I help you with?
What does high oxygen in water mean?
An oxygenated water (with a higher concentration of oxygen).
What happens to oxygen as the distance from the surface increases?
As the distance from the surface increases, the concentration of oxygen in the atmosphere decreases due to lower air pressure. This decrease in oxygen availability can make it harder for living organisms to breathe at higher altitudes.
Which gas is present in higher concentration in breathing air?
oxygen
How does oxygen get in to water?
Oxygen can enter water through the process of diffusion, where oxygen molecules move from areas of higher concentration (such as the atmosphere) to areas of lower concentration (the water). Oxygen can also dissolve in water when it comes into direct contact with the surface of the water, allowing oxygen molecules to mix and become distributed throughout the water.
What explains the fact that the net movement of oxygen is always into the cell?
The net movement of oxygen into the cell is primarily driven by concentration gradients. Oxygen concentration is typically higher in the extracellular environment than inside the cell, creating a concentration gradient that favors the movement of oxygen from higher to lower concentration. This allows oxygen to diffuse into the cell until equilibrium is reached, ensuring the cell has sufficient oxygen for its metabolic needs.
What process does a cell with a low concentration of oxygen will likely gain oxygen molecules from an area with a higher oxygen concentration have to go through?
The cell will undergo passive diffusion, where oxygen molecules move from an area of higher concentration to an area of lower concentration across the cell membrane. This process does not require energy and will continue until equilibrium is reached, with oxygen evenly distributed on both sides of the membrane.
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
Why does oxygen diffuses into the cells from the bloodstream?
Oxygen diffuses into cells from the bloodstream due to a concentration gradient, where oxygen is higher in the blood compared to inside the cells. This diffusion occurs passively, moving from an area of higher concentration (blood) to an area of lower concentration (cells), to meet the cell's energy demands for cellular respiration.
Why does oxygen always diffuse into an animal cell?
Oxygen diffuses into animal cells because of a concentration gradient. Oxygen is higher in concentration in the external environment or surrounding tissues compared to inside the cell. This difference in concentration drives the passive diffusion of oxygen into the cell to maintain balance.
What makes oxygen pass into the capillaries that surround these sacs?
Diffusion. O2 moves from an area of higher concentration to a lower concentration.
Which process do oxygen molecules move down a concentration gradient?
Oxygen molecules move down a concentration gradient through simple diffusion. This means they move from an area of higher concentration to an area of lower concentration until equilibrium is reached.
Is the oxygen less at high altitudes?
Yes. Air is less dense at higher altitudes, so the oxygen is at a lower concentration.
