Unformatted text preview: atmosphere doesnt play a vital role because phosphorus is typically a solid and found and observed at Earth level. The phosphorus is on the slowest cycles despite moving through plants and animals, because it moves through the ocean and soil very slowly. At first, phosphate is weathered from rocks and in soil clay surfaces and organic matter absorb it. Herbivores then eat plants and obtain phosphorus and then carnivores eat the herbivores and they receive the phosphorus. The phosphorus is then transformed into scat or poop from the animals. The oxygen cycle is the transfer of oxygen to the atmosphere, ocean, and lithosphere. Photosynthesis is the main driving force behind the oxygen cycle because it produces and releases oxygen into the atmosphere. When an organism dies, its shell is deposited on the seafloor and eventually is made into a limestone rock (lithosphere). Weathering processes can release this oxygen form the rocks into the atmosphere....
