Water
What is the chemical formula for Water?
H2O
Carbon is located here as coal, oil and natural gas.
What is a fossil fuel
Th process where decomposers like bacteria break dead matter down, returning nitrogen to the soil.
Decomposition
The negative human impact on the carbon cycle?
What is combustion
What does abiotic and biotic mean?
Abiotic means non living thing
Biotic means living thing
This drives the water cycle.
What is the sun
The process of animals taking in carbohydrates an oxygen and releasing CO2.
What is cellular respiration
Bacteria convert nitrogen in ammonia into nitrates and nitrites to be absorbed by plants in their roots
This is how nitrogen enters the food chain, and eventually reaches us.
What is nitrification
Use of fertilizers represents the negative human impact USUALLY associated with this geochemical cycle
What is nitrogen cycle
These 2 processes of the carbon cycle puts carbon dioxide back into the atmosphere.
What is cellular respiration and combustion
The sun heats liquid water to water vapor and it rises to the atmosphere.
What is evaporation
Carbon dioxide is released through burning.
What is combustion
Bacteria convert nitrogen from waste (urine and feces) into ammonia.
What is ammonification
The process that involves living organisms in the water cycle.
What is transpiration
This cycle does not involve matter changing chemical form as it moves through the cycle.
What is water cycle
Water seeps from the surface to underground aquifers.
What is infilitration
What is the process of decomposers breaking down carbon from dead organisms, allowing it to be recycled in the soil
Decomposition
Bacteria (or lightning!) in the soil or water convert nitrogen (from the air or water) into forms that plants can use
Nitrogen Fixation
This negative impact on the water cycle causes a decrease in infiltration.
What is building/pavement?
1. Which of the following is not an example of a biological process in a geochemical cycle?
A. Transpiration
B. Nitrogen fixation by bacteria
C. Erosion
D. Birds excreting waste into water
Erosion
Water condenses to form clouds before precipitating again
Condensation
What is the process of plants capture CO2 from the atmosphere and use it to make sugar
Photosynthesis
bacteria convert nitrogen in ammonia to N2 so it can go back into the atmosphere
Denitrification
This organism is highly involved with the nitrogen cycle.
What is bacteria?
Name two living organisms that are decomposers that are involved in the nitrogen cycle
Bacteria and Fungi
