What are the 4 Major components of earth's life-support system?
1. Atmosphere (air) 2. Hydrosphere (water) 3. Geosphere (rock, soil, % sediment) 4. Biosphere (living things)
100
What is a Trophic Level? List Examples?
-A Trophic Level is a feeding level -Ex: Producer, Primary Consumer, Secondary Consumers, Tertiary Consumers
100
Which of the 5 cycles is the slowest?
What is Phosphorus Cycle
100
What % of usable energy is gained through each trophic level?
10% ( 90% loss )
100
There is not a lot of Phosphorus in the soil what Human made /bat made items can increase the phosphate in the water and soil and in the end intefer with the cycle. (3)
What is Detergent,Guono,Fertilizer
200
How is life sustained in other words, what are 3 factors that sustain earth's life?
1. Sun 2. Nutrients 3. Gravity
200
Define the following terms: 1.Ominvore 2.Herbivore 3.Carnivore
1. Omnivore: Eats Plants & Meat 2. Herbivore: Eats only Plants 3. Carnivore: Eats only Meat
200
Equation for Photosynthesis
What is 6CO2 + 6H20 ---(light)--> C6H12O6 + 6O2
200
What happens as energy flows through the cycle?
The amount of energy through each trophic level decreases as you go up.
200
What is the Carbon Cycle?
Decomposers release carbon atoms stored in dead bodies and release them into the atmosphere, CO2 can remain in the atmosphere for over 100 years. Atmosphere removes too much CO2 -> temperature gets warmer. Decomposers release carbon that can be stored as insoluable carbonates in the bottom sediment for very long periods of time

Place the following terms in order from on earth to farthest away: Troposphere, Hydrosphere, Geosphere, Atmosphere,Stratosphere
[Starting from on earth to farthest away] Interchangeable{Hydrosphere {Geosphere Atmosphere Trophosphere Stratosphere
300
What is a Decomposer? Give an Example.
-Decomposers release nutrients -Examples: Fungi and Bacteria
300
Describe the steps of the water cycle. Include the following terminology: Evaporation,Condensation,Precipitation,Runoff,Groundwater and Transpiration
What is The sun heats the water which causes the molecules of water to rise into the atmosphere. This is called Evaporation. Condensation is when these molecules turn into droplets. Precipitation is when this water is released. Most of this water is considered Runoff. Some gets stored in aquifers as ground water and some return back into the oceans. Transpiration is when water on the plants evaporates off of the plants.
300
What is Biomass
dry weight of all organic matter contained in organisms
300
What is Nitrification?
What is When bacteria turn Ammonia (NH3) to Ammonium (NH4+)
400
aye fissssssss u r a fissssss ahahahaha..... bye i gots to go
aaaaaaaahaaaaa
400
What is a Detrivore? Give an Example.
Detrivores feed on waste of dead organisms Examples: Earthworms, some insects
400
What cycle is Nitrogen Fixation a part of and what is it?
What is Nitrogen Cycle. Process where Bacteria "fix" the Nitrogen and turn Nitrogen Dioxide into NH3 (Ammonia)
400
What is GPP
Gross Primary Productivity. Rate at which producers convert solar energy into chemical energy in their body
400
Describe the Phosphorus Cycle ( NO ATMOSPHERE)
Overtime the ocean sediment and rocks wash away over time which releases the phosphate into the water supply which carry them into the soil where they are consumed by plants. Then the phosphorus is transferred through the food web and decomposers release this back into soil. Some phosphate can also be lost and can settle in the ocean or in the soil which can re start the cycle.

Name each level 4) Lion 3) Fox Dog Bird 2) Hare <-| |-> Caterpillar 1) Grasses
1. Primary Producer 2. Primary Consumer 3. Secondary Consumer 4. Teriary Consumer
500
Describe the Sulfur Cycle?
Hydrogen Sulfide and Sulfur dioxide is released by volcanoes (DMS) and anaerobic decomposers found in Swamps and Bogs. DMS is converted into SO2,SO3, and sulfuric acid (H2SO4). Acid Decomposition occurs when the DMS reacts with ammonia. (Rain,Snow,Sleet,Hail)
500
What is NPP?
Net Primary Productivity. Rate at which producers use photosynthesis minus stored energy through aerobic respiration
