Hello, Geny5!! The sun has six complete layers in total. The first outer layers are named the corona, chromosphere, and the photosphere. The other inner three layers are named convective zone, radiative zone, and the core. The structure of the sun goes (outer to inner) corona, chromosphere, photosphere, convective zone, radiative zone, and then the core. The corona is a thick layer of gas which surrounds the sun by many, many miles around the sun. The chromosphere is a thin layer of gas above the photosphere, also forms the structure of the sun. The photosphere is extremely hot, gives off light, and is the part that can be seen. The convective zone carries the energy under the surface. The radiative zone is where energy from the core goes through, but it takes a lot of time for it to go out of the radiative zone. Finally, the core is the absolute hottest part of the sun because it produces so much energy to the sun, making it shine. I hope this helped!! Have a great evening!!
The elodea is getting the carbon dioxide from its environment like when underwater animals breathe out carbon dioxide the plants will use that carbon dioxide. The plants can also get the carbon dioxide from the atmosphere which can "dissolve" in water.
