Terminology
What is biotic and abiotic
Biotic-Living things
Abiotic-Non Living things
What is the purpose of a nutrient reservoir?
A nutrient reservoir is used to hold substances for a period of time before passing to another reservoir.
What is Nitrification?
A two step process where nitrifying bacteria change ammonia or ammonium to nitrites then nitrates
Put these two words in the same order.
_____ system allows energy and mater to enter and leave the system.
_____ system does not allow matter or energy to leave the system.
Open, Close
Which producers convert energy from chemical bonds into stored biological energy. They provide much less energy but allow life to exist in extreme environments on earth?
Chemosynthetic producers
What is Albedo
Literally means "whiteness" The amount of light an object reflects.
What is it called when there is and excessive amount of nutrients ( phosphates and/or nitrates) in water?All oxygen gets used up in the water and no other living things can survive.
Eutrofication
What are 3 examples of slow cycling carbon
Volcanic eruptions, Weathering and erosion, organic deposits
What are the two laws of Thermodynamics?
1. Energy cannot be created or destroyed, only transferred.
2.energy conversion is not a 100% efficient some energy is lost to sound heat, ect.
What is Biosequestration?
Taking fuel or separated carbon dioxide and "storing" it in algae or bacteria that use it for photosynthesis
What does Polarity mean?
Water is two sided, with the hydrogens pulling toward one side with a positive charge and the oxygen on the other side with a negative charge.
True or False. Plants use nitrogen gas.
Which cycle does not include the atmosphere
Sulfur cycle
These produce dead spots in the ocean.
Algae blooms
Why is carbon dioxide a GHG where as nitrogen is not?
Carbon dioxides absorbs infared radiation producing heat and keeping the energy near the earth. Nitrogen gas does NOT absorb Infared light well thus allowing reflected light to escape into the atmosphere
What is Transpiration
Plants breathing out water vapor
Which cycle is not found in the atmosphere?
Phosphorus
Where is the largest nutrient reservoir on earth?
In the earths crust
True or False. Biodiversity decreases the stability of food webs/ ecosystems
False. it Increases the stability
What are Stromatolites?
As bacteria dies they create sedimentary rock with bands of iron oxide
What is Pyrolysis?
The heating up of organic material in the absence of oxygen.
True or False. Plants use water soluble sulfer.
True they use Sulphates which is combined with water
What are the 5 steps of the oxygen cycle?
1.Photosynthesis 2.Cellular respiration 3.Decay and Decomposition 4.Combustion of organic matter or fossil fuels 5. Dissolving
Why is a Pyramid of energy the only pyramid to actually be in the shape of a pyramid?
Because the energy is changing, Loss of energy per a level.
What are the 3 things that happen to sunlight that reaches the earth?
1.Reflected 2.Absorbed 3. Transmitted
