Energy for life processes

organisms organized according to how they obtain energy
	autotrophs
		"producers"
		use photosynthesis AND cell respiration
		convert light energy from sun into chem. energy
		i.e.
			plants
			some bacteria
			algae
	heterotrophs
		"consumers"
		cell respiration
		i.e.
			animals
		eat autotrophs
biochemical pathway
	product of one reaction is consumed in the next
	photosynthesis &respiration
	6CO2 + 6H2O -> C6H12O6 + 6O2
	C6H12O6 + 6O2 -> 6CO2 + 6H2O
photosynthesis
	complex series of chemical reactions
	anabolic reaction
	endogonic- energy storing
	Radiant Energy -> chemical bond energy
	energy is found in the carbon-hydrogen bond
	enzymes and chlorophyll are necessary
