Document Summary
Cycle: flow of key chemical elements that move substance 1 place another. System: network of relationship that influence energy exchange. Negative feedback loop: output result from system input in opposite direction (neutralize) Positive feedback loop: drive system to further extreme. Resilience: readily system will return to original state once disturbed. Emergent properties: characteristic not evident in individual component on own. Geosphere: rock/sediment of solid earth (thick of plant outermost layer) Hydrosphere: all of water, salt, liquid, ice, vapour, water bodies. Cryosphere: frozen parts of hydro (glaciers, snow, land ice) Gross primary production (gpp): convert solar energy to energy of chemical bonds by autotoph. Net primary production (npp): energy remains after respiration to generate biomass. Secondary production: total biomass that heterotrophs generate by consume auto.
