Oxygen enters seawater through diffusion from the atmosphere at the water's surface and through photosynthesis carried out by marine plants and phytoplankton.
Chemical weathering and out gassing
Water is a compound. Seawater is a mixture containing salts as well as water.
Oxygen dissolves in water from the air, where it enters the water through the process of diffusion. Additionally, aquatic plants and algae release oxygen as a byproduct of photosynthesis, contributing to the overall oxygen content in water.
Carbon Dioxide (CO2) and Oxygen (O2) can enter leaves through the pore.
Oxygen can dissolve in water through direct diffusion from the atmosphere at the water's surface. Oxygen can also be produced through photosynthesis by aquatic plants and algae, increasing oxygen levels in water.
Two sources of oxygen in seawater at the surface include atmospheric exchange, where oxygen from the air dissolves into the water, and photosynthesis by marine plants and phytoplankton, which produce oxygen as a byproduct.
by rivers
They are the hydrogen and oxygen of the water itself. After that it's chlorine and sodium.
From another river, from a spring, from rain etc
the water
carbon dioxide goes out and oxygen comes in
skin surface (integumantary system) and the lungs (alveoli) .
Two ways to increase oxygen pick up by mammals would include breathing more deeply and breathing more rapidly
the air and oceanic plants
extract air bubbles from water
Food and Oxygen
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
