In the previous chapter on environmental response, we considered the various ways that individual organisms respond to the physical, chemical and/or biological stimuli in their environment.In this chapter, we will go deeper into the interactions between the biotic and the abiotic elements of the biosphere, focusing on the nonliving components. To begin to understand this concept: the physical "home" of our biosphere, we first have to consider the physics of planet formation. From all we know about life in the universe, only planets can possibly offer conditions suitable for life. And indeed, since all life we know of occurs on just one planet, we need to develop an understanding of what is special or unique about our home planet. How is the earth constituted; what is the nature of this "stage" upon which life developed and upon which life continues to play out. Presently, the "ecology" of other planets, if such a thing exists, is a subject of study within the science of exobiology.
Nutrients move through the ecosystem in biogeochemical cycles. A biogeochemical cycle is a circuit/pathway by which a chemical element moves through the biotic and the abiotic factors of an ecosystem. It is inclusive of the biotic factors, or living organisms, rocks, air, water, and chemicals. The elements that are moving through the biotic or abiotic factors may be recycled, or they may be accumulated in a place called a sink/reservoir where they are held for a long period of time. The amount of time that a chemical is held in one place is called residence.
All of the chemical elements in an organism are part of the biogeochemical cycle. The chemicals travel not only through the biotic and abiotic components of an ecosystem, but they also travel through an organism. The abiotic factors of an ecosystem include: (1) water (hydrosphere), (2) land (lithosphere), and (3) air (atmosphere). All of the living factors that are found on Earth make up the biosphere.
