CARBON CYCLE 1. Photosynthesis/Respiration link 2. Carbon cycles fast (plants have high demand) 3. Decomposition recycles carbon to atmosphere 4. Fossil fuels (Coal , oil, natural gas)  5. In aquatic environments: dissolved CO 2  reacts with water to form carbonic acid,        which reacts with limestone to form bicarbonates and carbonate ions • reservoirs: atmosphere (CO 2 ); fossil fuels, organic material • assimilation: photosynthesis; animal consumption • release: respiration; decomposition; combustion

NITROGEN CYCLE - Atmosphere is about 80% nitrogen, but not in a usable form 1. Nitrogen Fixation a. reduces atmospheric nitrogen to ammonia (NH 3 ) b. prokaryotes (Rhizobium bacteria; cyanobacteria) c. also by lightening (small amounts)      d. eventually, all organisms depend on this process for nitrogen 2. Nitrification      a. oxidation of ammonia (NH 3 ) to nitrite (NO
