AP Biology Photosynthesis Part 4

Energy Flow and Matter Cycling Tertiary consumers Microorganisms and other detritivores Secondary consumers Primary consumers Detritus Primary producers Heat Key Chemical cycling Sun Energy flow

Carbon Cycle Higher-level consumers Primary consumers Carbon compounds CO2 in atmosphere Photosynthesis Cellular respiration Burning of fossil fuels and wood Higher-level consumers Primary consumers Carbon compounds in water Detritus Decomposition

Food chains and the 10% Rule of Energy

10% Rule Plant material eaten by caterpillar 200 J 67 J Cellular respiration 100 J Feces 33 J Growth (new biomass)

Food web of the Arctic ocean

Productivity of the Earth (Based on Chlorophyll Density) Red And Yellow areas have the highest productivity…so where are they located?

Rising CO2 and rising average global temperature

Melting Antarctic Ice due to increased water temperature

Net Primary Productivity NPP = GPP - R
