- ◦A Ecosystem is al the interacting parts of a biological community and it's enviorment.
- ◦E.g.- Sahara Desert, Rain forest.
-
What is a sustainable ecosystem?
This is an ecosystem that is capable of withstanding pressure and giving suppourt to a variety of organasims.
-
What does the word Biotic mean?
- ◦Biotic means the living parts of an ecosystem
- .E.g.- Animals, plants, micro organasims, Fungi, bacteria, Ect...
-
What does the word Abiotic mean?
- The non living parts of an ecosystem.
- E.g.- Water, sunlight,light Ect...
-
What is the earths four spheres?
- ◦LithoSphere
- ◦BioSphere
- HydroSphere
- ◦Atmoshere
-
What is the LithoSphere?
- ◦The LithoSphere is the hard part of the earths surface.
- ◦E.g.-Rock and Dirt.
-
What is the Hydro Sphere?
The hydro sphere is all the water on the earth including lakes. oceans and ground water.
-
What is the atmosphere?
- ◦This is the layer of gases above earths surface.
- ◦E.g.-Air
-
What is the Bio Sphere?
The reigons of the earth where living organasims exist.
-
What are Nutrients?
Nutrients are a chemical that is essential to living things and is cycled through the ecosystems.
-
What is Eutrophication?
This is a process in which nutrient levels in aquatic ecosystems increases leading to aan increase in the popoulation of primary producers.
-
What is photosynthesis?
This is a process that changes solar energy into chemical energy.
- In brackets means towords the bottom right of the letter and smaller then the letter.
- Equation= 6CO(2) + 6H(2)-----> C(2)
- H(12) O(6) + 6O(2).
-
What is Trophic Level?
Trohic level is a category of organasims that is defined by how the organasims gain their energy.
-
What is tropical Efficiency?
- Trophical efficiency is a mesure of the amount of energy or biomass transfered from one trophic leve to the next higher trophic level.
- When an animal eats another animal the animal only gets 10% energy from the animal. This is because the other animal uses energy and it could be because the curret animal didn't eat the whole animal.
-
What is biomass?
Biomass is defined as being the total mass of living organasims in a defined group of area.
-
What does the word bioaccumulation mean?
Bioaccumulation is a process in which materials especiallyy toxins are ingested by an organasim at a rate greater then they are elimnated.
-
What is Biomagnification?
Biomagnification is the increase in the concentration of a toxin as it moves from one trophic level to the next.
-
What is cellular resperation?
Cellurlar resperation is a process that releases energy from organic molecules, especially carbohydrates, in the presence of oxygen. (Aerobic)
-
What is Fermentation?
This is process that releases energy from organic molecules, especially carbohydrates in the absense of oxygen.(Anerobic)
-
What are green house gases?
- They are atmosoheric gases that prevent heat from leaving the atmosphere, thus increasng the tempature of the atmosphere.
- The green house gases are- Water vapor,Carbon Dioxide and methane.
-
What is Green house affect?
Green house effect is the warming of earth as a result of green house gases, which trap some of the energy that would otherwise leave earth.
-
What is Acid precipitation?
Acid precipitation is rain, snow, or fog that is unnaturally acidic due to gases in the atmosphere that react with water to form acids.
