Evolution: change in inherited traits of a population of organisms through successive generations levels of ecological organization: organism, population, community, ecosystem, biosphere (sum of all) Sun - driver of ecosystem, energy comes in and leaves as heat. Energy passed through food chain, large amt of energy used for metabolic processes inorganic nutrients cycled through ecosystem. Decomposers eat dead things, give off heat, recycle nutrients. Pyramid: producers (plants), primary consumers (herbivores), secondary, tertiary, quaternary (carnivores) Only 10% of energy is transferred from one level to next, rest is lost.
