|
Gaia theory |
Living things are in the earth to proved life for each other |
|
|
|
Biochemical cycle |
Life within soil |
|
|
|
Carbon cycle |
-An atmospheric cycle -“Green house effect” Combustion-fossil fuels -Photosynthesizers Break down CO2 |
Pollution |
|
|
Nitrogen cycle |
Atmospheric cycle 1. Nitrogen Fixation= N2 has converted for bacteria use 2. Ammonification= bacteria break down nitrogen into ammonia 3. Nitrification= Convert ammonia back to NO3 Leaves soul into atmosphere 4. Dentrification= NO3 converted back to atmosoheric N2 gas |
4 steps |
|
|
Root nodules |
Accomplish nitrogen fixation |
Aid in a cycle |
|
|
Sulfur cycle |
-sulfur in the environment not in atmosphere -bacteria helps break down soil -sulfur in water sources |
|
|
|
Phosphorous cycle |
-all life depends on it -phosphorus in DNA, RNA, ATP |
|
|
|
Bio accumulation |
Increasing numbers of toxic substances Ex] fish eating mercury |
|
|
|
What are the 3 layers of the lithosphere ? |
1. Humus= -rich layer -animal + plant debris being decomposed 2. Rhizosphere= -deeper into soil - plant roots -fungus helps plant grow 3. Mycorrhiza= -symbiotic relationship between plant + fungus -plants give the fungus food |
|
|
|
Hydrologic cycle |
-rain/ snow comes down -snow/ice melts -goes into soil -into fresh water areas -ocean Evaporated -Rain/snow |
|
|
|
Zoo plankton |
-microscopic consumers -filter, feed, prey, scavenge |
|
|
|
Epilimnion |
Top of the lake |
|
|
|
Hypolimnion |
Deeper cooler water of a lake |
|
|
|
Thermocline |
-between the epilimnion + hypolimnion -prevents the mixing of cold and warm lake water |
|
|
|
Oligotrophic |
-nutrient deficient ecosystem -no microbes in that environment -full of pollution |
|
|
|
Eutrophication |
-excess nutrients -agriculture -large number of people + animals= competition -environment cannot sustain large numbers |
|
|
|
Potable |
Water that is clean to drink |
|
|
|
Standard plate |
Looks for number of colonies in water |
|
|
|
Biological oxygen demand (BOD) |
Lols for aerobic/ anaerobic microbes in water |
|
|
|
Membrane filter method |
-after filtration -checks to see what microbes were left in water |
|
|
|
Littoral zone |
-not deep into water -warmer water -photosynthesizers |
|
|
|
Most probable number (MPN) |
Takes water sample and looks for the number of contaminents -confirmatory test |
|
|
|
Limnetic zone |
-Deeper water -colder water -can contain photo synthesizers -contains microbes that eat photosynthesizers |
|
|
|
Photic zone |
Surface of water to the lowest limit of sunlight penetration |
|
|
|
Profundal zone |
-edge of photic zone -deep water |
|
|
|
Benthic zone |
-dead organisms -basin of the lake |
|
|
|
Estuary |
Where salt water meets fresh water |
|
|
|
Abyssal zone |
-deep zone in the ocean -cannot be reached by human without exploding |
|
|
|
Plankton |
-support large invertebrates + fish -floating microbial community that drifts with waves + currents |
Food |
|
|
Photo planktons |
Photosynthesize algae |
|
