Carbon Path: Atmospheric CO2: this arises from geological sources such as volcanoes, burning fossil fuels, etc. This gets carbon dioxide back into the atmosphere during these processes.
2. Path G (Geosphere)
Carbon Path: Lithosphere: Earth’s carbon has been researched to have large limestone deposits. This limestone can be found in the Earth's lithosphere. Through the heating of limestone, carbon dioxide gets back to the atmosphere.
3. Path H (Hydrosphere)
Carbon Path: Oceania CO2: there is a large deposit of dissolved CO2 underneath the ocean. As the ocean gets colder, it dissolves more. The plants absorbed carbon dioxide through photosynthesis and get back to the atmosphere

Aquatic plants don't have to deal with drying stress, so, for example, the number of stomas will be lower or even absent. Also, the pressure and temperature conditions underwater are way different than on earth. Therefore, the movement of fluids and metabolic products will be quite different.
The sporophyte stage is the predominant phase in ferns. They have specialized water and nutrients conducting tissues called xylem and phloem that differentiates them from mosses. ... The sporophyte obtains its nutrition from the dead and decaying organic matter
Basically, what you need to do is use a term for each one of the circles so it is even and if you look at the explanation(above or below it) it will match the definition of the term you provided. I'm guessing tho.
