Nutrient Cycle
Archae domain
Energy vs. Nutrient Movement
Ecological Succession
Has only one kingdom called Archaebacteria
Is the oldest/ most ancient domain
Distinguishing Features:
Energy
Matter
ecological succession- changes to an ecosystem
primary- start from scratch
secondary- regrowth
Prokaryotic
Unicellular
Cell wall – no peptidoglycan
Autotrophs & Heterotrophs
Extremophiles
Motile
Energy flows through ecosystems. The energy that flows through an ecosystem is transferred through feeding. Every time the energy is transfered alot of it is lost. The loss of energy that is flowing through an ecosystem is called Entropy.
matter cycles through ecosystems meaning that it is reused over and over and because of the law of conservation of matter no matter can be lost in the cycle. The cycles are simply matter transforming into diffrent forms. A common example of this is the water cycle.
No soil
Pioneer species: lichen moss
Rare
Volcano
Soil already present
Common
Fire, clear cutting…
Prokaryotic means that they don’t have an organized nuclei
Unicellular means that they are made up of only one cell
Autotrophs produces there own food/ energy typically through Photo/ Chemo synthesis
Heterotrophs consume other organisms in order to survive
Extremophiles can survive/ thrive in extreme temperatures
can move around (synonym of mobile)
Methods of moving around:
types of cycles
pseudopod
cillia
Water
Carbon
Nitrogen
Phosphorus
Oxygen
In this method of locomotion in which it extends a “fake foot” and then drags itself towards the “fake foot”
Water in the ocean and other bodies of water evaporate. Also in hot climates the water absorbed from roots is sometimes released as a vapor from the leaves along with other gasses such as oxygen. This is called evatranspiration. Also some water sublimates which is when solids turn directly into a gas. After water is sublimated, evaporated and or sublimated the water begins condensation which is water vapor begins to turn into a liquid. Once alot of water is condensed the water begins to fall which is called Precipitation. During precipitation water can fall as a rain, snow, or hail. When the snow falls on mountains it begins to melt and when it does the water run off to streams. Some of the water also seeps into the ground and the eventually runs of into a body of water. Then the cycle can begin again.
Where the CO2 comes from
Transformation
CO2 is contently being emitted by humans and other animals exhaling. Also cars and factory emissions create CO2. dead organisms and plant respiration also contribute CO2.
The CO2 that is created is then absorbed by trees which then transform the CO2 into oxygen which alows us to inhale thus, starting the cycle all over again.
