Document Summary

They do not reflect on how related the organisms are from each other or whether they have a common ancestor. Ex: wings of bird and bats are analogous, because they developed independently to adapt to a common function. During the sedimentation of calcium carbonate, which is insoluble to water, carbon dioxide turns into bicarbonate to carbonate and then to calcium carbonate, which becomes sedimentary rock.

The global circulation of carbon atoms, especially via the processes of photosynthesis and respiration. Marine and terrestrial components of the global carbon cycle are linked through an atmospheric reservoir of carbon dioxide.
