Nitogen cycle
|
Convert nitrogen into useable forms
- soil bacteria convert nitrogen into ammonium -soil bacteria convert ammonium into nitrate - plants absorb both forms of nitrogen - bacteria converts nitrate back into nitrogen gas into atmosphere - Excess nitrate and ammonium eventually enter the lithosphere - |
Plants- N2- NH4+- NO3-
|
|
Water cycle
|
Ice and snow- ground water- run off- ocean water- evaporation - sun - condensation - precipitation
|
|
|
Carbon cycle
|
Carbon released into atmosphere when fossil fuels burned
-carbon stored in vegetation - used in photosynthesis to produce carbohydrates -carbon in soil - decaying plants produce carbon -carbon stored in fossil fuels and released when burned -plants eaton by animals - carbon released into atmosphere during respiration of animals and plants - into vegetation again - |
|
|
Phosphorus cycle
|
Stored in lithosphere
-rocks break and phosphate is released into soil -phosphate absorbed by plants through roots - bacteria break down dead organisms releasing phosphate back in soil |
Causes EUTROPHICATION ( deposits of excess nutrients)
Ex. Lake Erie, overgrowth in algae by 30 times upsetting natural balances |
|
Abiotic
|
Non-living factors/parts of an ecosystem
|
ex. Water, oxygen, light, nutrients, soil, rock
|
|
Biotic
|
Living part of an ecosystem
|
Ex. Animals, plants, bacteria
|
|
Symbiosis
|
Interaction between members of 2 different species
|
Fish eating bacteria off of shark
|
|
Predation
|
1 organism eats/consumes another organism for food
|
|
|
Competition
|
2 or more organisms compete for the same resource
|
|
|
