Atmospheric CO2 comes from volcanoes, burning fossil feuls, animals exhaling, forest fires etc
Co2 dissolves in the ocean. Cold water dissolves more CO2. lots of CO2 in the deep depths of the ocean
co2
Marine plants and algae do photosynthesis by using co2 and water. it makes glucose and oxygen
co2
marine animals get their energy by eating Marine plants and algae.these animals do cellular respiration by taking in oxygen and eating plant glucosethis releases CO2 and water
CO2
co2
uneaten marine animals drift down to the ocean floor and the sediments consumes them which stores the carbon
