Capture and transfer light energy to chemical bonds
Not a perfect process – some energy is lost - entropy
Absorption spectra of chlorophylls and carotenoids
Wavelengths not used - reflected
CO2 enters passively so stomata have to be open for long periods of time
C3 grasses (yellow) dominant in cool temperate – C4 plants don’t compete so well there
C4 grasslands (orange) have evolved in the tropics and warm temperate regions
How do animals respond?
Cecum is site of much bacterial activity, moist fecal pellets enclosed in protein produced
Widest ranging of otters
Diet varies with abundance of prey
