Biogeochemical Cycles
Nitrogen Cycle
Carbon/Oxygen Cycle
Water Cycle
Vocabulary
100
This cycle involves ALL living and nonliving components found on Earth.
What is the biogeochemical cycle?
100
This element accounts for 78% of the gasses found in our atmosphere.
What is Nitrogen?
100
This element is the building block for all living things.
What is Carbon?
100
All living things on Earth require this element to survive.
What is water?
100
In this process, water moves from the Earth's surface to the atmosphere with the help of the Sun's solar radiation.
What is evaporation?
200
Biology, geology, and chemistry are all involved in this cycle.
What is the biogeochemical cycle?
200
This location is the largest reservoir for Nitrogen.
What is the atmosphere?
200
This is one of two ways carbon can move from the atmosphere to the water or water to the atmosphere.
What is dissolve into the surface water or evaporate into the air?
200
This object gives the Water Cycle all its needed energy.
What is Sun?
200
In this process plants take water and carbon dioxide and convert it into sugar and oxygen.
What is photosynthesis?
300
This process is another natural way that Carbon can enter into the atmosphere.
What is volcanic eruptions or weathering of rocks?
300
This organism is a key player in the Nitrogen Cycle.
What is bacteria or decomposers?
300
This is one way humans add Carbon into the Carbon/Oxygen Cycle.
What is burning fossil fuels?
300
This is the second largest freshwater reservoir on Earth.
What is groundwater?
300
In this process, living organisms take in oxygen and release carbon dioxide.
What is cellular respiration?
400
This event in the water cycle would most likely slow down or stop if trees and other large plants were cut down.
What is transpiration?
400
This is one way humans add nitrogen into the Nitrogen Cycle.
What is burning fossil fuels?
400
These three organisms play a huge role in the Carbon/Oxygen Cycle.
What are producers, consumers, and decomposers?
400
About 2% of all Earth's water is in this form.
What is Ice?
400
Precipitation seeps into the ground and becomes groundwater--this water tends to be filtered and clean.
What is Infiltration?
500
Marine organisms like coral and shellfish have carbon in their bodies as this form.
What is calcium carbonate?
500
Nitrogen-fixing bacteria convert nitrogen into these two compounds.
What is ammonia and nitrates?
500
The carbon/oxygen cycle is strongly connected to this biological process.
What is photosynthesis?
500
Water in the atmosphere exists mainly in this form.
What is water vapor?
500
Plants lose water by way of evaporation through the surfaces of their leaves.
