Let's take this one step further. The land is an organism even if there is no life, even if there are only rocks and the elements. On this inorganic land there remains a system of interdependent processes just as in your skin-covered organism. We call these processes by physical names such as erosion, mountain building, exfoliation, adsorption, freeze expansion, and so forth. This system of interrelationships exists and functions just the same as in any living organism.
Processes depend on other processes.
Systems depend on other systems. For example, weather erodes rock into sediment which may filter water for a while before it gathers into sedimentary rock which may compress into metamorphic rock, which may then crystallize into valuable minerals or may erode back to sediment. This last serves humans and all other organisms as the medium in which all interconnections of life take place. That energy connects each of us with every other species and with every piece of land and with every piece of star in the universe. But let's leave the fourth level for another discussion.
