Document Summary

Conservation of matter cannot be created/destroyed, only transformed: 4 states: solid, liquid, gas, plasma, changes as you add more energy. Components of systems: pools (state variables) quantity of interests stored fluxes transfer between pools fish eating a plant system: jungle pool: animals flux: a lion eating its prey. Open v. closed systems: closed no inputs or outputs, open system inputs or outputs to/from outside the system. Equilibrium in systems aka homeostasis things are staying within a range. Energy cycling in ecosystems first law of thermodynamics energy cannot be destroyed, only transformed: second law of thermodynamics energy goes from a more ordered state to a less ordered state.

Light dependent reactions energy comes from the sun and produces atp and nadh. Light independent reactions co2, h2o and energy sugars + o2. Cellular respiration sugars broken down to produce energy for something else.
