Document Summary
Central case is belugas in st. lawrence dying from gi cancer. Networks of relationships among parts, elements, cycles etc. that influence one another through the exchange of energy, matter and information. Open systems: energy and matter is exchanged. Negative feedback: system moves in one direction acts as input that moves the system in the other direction. Positive feedback: they don"t stabilize the system. When processes within a system move in opposing directions at equivalent rates so that their effects balance out dynamic equilibrium is achieved. Anthroposphere: all parts of environment that are built or modified by humans. The majority of energy taken in is lost through respiration, the excess is released as heat. Conversion of solar energy to energy of chemical bonds in sugars by autotrophs = gross primary production (gpp). The remaining energy after respiration= net primary production (npp). The total biomass heterotrophs generate by consuming autotrophs= secondary production.
