Carbon is exchanged in biosphere by photosynthesis
Well carbon is in pretty much everything in certain ways.
Photosynthesis? I heard that before. Isn't that how plants use sunlight to make food from carbon dioxide and water?
Right! That's correct. The food that plants make contain sugar which contains carbon.
So is the hydrosphere made up of all the water on Earths surface?
Yes! The CO2 is constantly exchanged between the water surface and the air by photosynthesis and cellular respiration. This is done by the organisms closest to the surface.
A lot of the CO2 that is absorbed from the atmosphere can be converted into calcium carbonate (CaCO3) or bicarbonate (HCO3-) that many ocean animals rely on.
Wow Dad I didn't know that you know so much about hydro and biosphere. thanks for your help.
No problem son now go get some sleep.
The interaction can help us by providing enough food and water to drink. It can also help us by creating oxygen for us to breath and survive. The flood gives us rich solids. But the interaction doesn’t help us because the flood can destroy the town, and also kill a lot of living things.
