Atmosphere-Biosphere
What is the first step of the Oxygen Cycle?
100
Photosynthesis from producers such as trees.
What is the first step of the carbon cycle?
100
When the atmosphere is full of Nitrogen Gas, Nitrogen Fixation occurs.
What is the first step of the Nitrogen Cycle?
100
Oxygen would eventually become trapped in reservoirs and no longer available for the organisms that rely on it
What would happen if oxygen could not be cycled?
100
DNA and Proteins.
What critical component of the foundational molecules that make our bodies?
200
Atmosphere-Hydrosphere
What is the second step of the Oxygen Cycle?
200
Consumption from consumers such as cows.
What is the second step in the Carbon cycle
200
Bacteria converts to Nitrites and Nitrates, which are taken up by the plants to use as nutrients.
What is the second step of the Nitrogen Cycle
200
Atmospheric nitrogen becomes part of living organisms in through bacteria in the soil that form nitrates out of nitrogen in the air.
Why is the Nitrogen Cycle essential?
200
Photosynthesis is the driving force. When Living organisms take in oxygen gas and convert it to carbon dioxide during respiration
What is the driving force for making oxygen available for life?
300
Biosphere-Hydrosphere
What is the third step of the Oxygen Cycle?
300
Dissolved and Segmented into bodies of water
What is the third step of the Carbon Cycle?
300
Consumers gain nitrogen when eating plants, die, decompose.
What is the third step of Nitrogen Cycle?
300
All living organisms are built of carbon compounds. It is the fundamental part of life and an important component of many chemical processes.
Why is the Carbon Cycle important?
300
The sun allows Photosynthesis to occur, therefore plants can create energy/oxygen.
How does energy from the sun drive Earth's carbon cycle?
400
Biosphere-Lithosphere
What is the fourth step of the Oxygen Cycle?
400
Burned fossil fuels for factories/ atmosphere.
What is the third step of Carbon Cycle?
400
Decomposition of consumers convert to Nitrogen gas which is than released into the air.
What is the fourth step of the Nitrogen Cycle?
400
This process meant that the food supply made available for humans was no longer limited by the nitrogen fixation of natural bacteria.
What positive effect did the Harbor-Bosche process have?
400
Atmosphere, Earth, BioMass, Oceans.
Where are Carbon Reservoirs found?
500
Oxygen is a molecule made of two oxygen atoms. Living organisms use this oxygen to break down food to release energy. Ozone is a molecule made of three oxygen atoms. It forms a layer in the Earth's atmosphere where it absorbs the majority of the harmful UV radiation from the Sun.
What are the main differences between oxygen and ozone in terms of structure and use for living things?
500
Fossil fuels are materials that store energy and are formed by natural processes such as the decomposition of dead organisms buried in the Earth.
What are fossil fuels?
500
The conversion of nitrogen is carried out through the nitrogen cycle including fixation, ammonification, nitrification, and denitrification.
What is the role of microorganisms in Earth's nitrogen cycle.
500
Caused severe imbalances in the nitrogen cycle of some ecosystems. When excessive nitrogen is present in soil due to fertilization, the extra nitrogen, usually as nitrates, leach into water runoff and can make its way to human drinking water. Or, the extra nitrogen compounds can flow to rivers and marine ecosystems.
What negative effect did the Harbor-Bosche have?
500
Coal, Limestone, Carbohydrates, etc
What are examples of carbon forms found on Earth?
