Biogeochemical Cycles The Biogeochemical Cycles Human Impact on the Carbon Cycle Photosynthesis: Deforestation - less carbon from the atmosphere into biomass. Afforestation - more carbon from the atmosphere into biomass. Marine pollution w...

Untitled While the air we breathe is rich in nitrogen gas (N2) and is the major component in air at 78%, this nitrogen is unavailable to us since nitrogen gas is very inert chemically. We want to briefly discuss how nitrogen g...

Nitrogen Cycle Nitrogen CycleAmmonification:Saprobiotic microorganisms feed on urea found from the ammonium containing compounds.They release NH3 as they do so, then it is converted to NH4+ in ammonification in the soil.Nitrificatio...

The Nitrogen Cycle Revision The Nitrogen Cycle Revision Nitrogen is a vital element for all living things. It is needed to make proteins. Proteins themselves are needed as raw materials for the building of new cells and repairing the old cells.&...

Cycles Carbon Dioxide - Oxygen When carbon is inside an animal it is part of the biosphere but when it is outside the animal it is part of the atmosphere Carbon is not always in the form of carbon dioxide Cellular respiratio...

Nitrogen Cycle 1. NITROGEN FIXATION Nitrogen gas (in atmosphere) is converted into ammonia by bacteria called Rhizobium. Ammonia is then used by plants. Rhizobium found inside root nodules of leguminous plants (e.g. peas, beans and ...

Nitrogen Fixation, nitrification and denitrification Nitrogen fixation Impossible for plants to use nitrogen gas directly because it is very unreactive. Instead they need a supply of fixed nitrogen such as ammonium ions or nitrate ions. Can occur when lightning strikes ...

the water cycle THE WATER CYCLE Accumulation- the process in which water pools, or accumulates, in large bodies like oceans, seas, or lakes. Evaporation- the process in which liquid water becomes water vapour (a gas). Water vaporizes...

11 The carbon cycle Carbon dioxide is removed from the environment by green plants and algae during photosynthesis The carbon from the carbon dioxide is used to make carbohydrates, fats and proteins, which make up the body of plants and ...

Carbon Cycle 1) One arrow from atmosphere which is photosynthesisCO2 is removed by plants and algae.2) Some carbon is returned to the atmosphere by plant respiration. Some is eaten by animals when plants are eaten.3) Some carbon i...

Untitled Nitrogen Fixation: It is the process of conversion of atmospheric N2 to soluble form by roots of plants. Steps: 1. Ammonification: Plants make their protein using soluble form of N2. From plant it passes to anim...

Nitrogen cycle Nitrogen fixation:78% of atmosphere is made of nitrogen. N2 is a very stable molecule so will not take place i any reactions so cannot be used by plants if animals as a source of Nitrogen. The N2 is turned into ammoni...

Untitled Ammonification: Dead animals/waste products are decomposed by saprobiotic bacteria. They secrete digestive enzymes, breaking down complex molecules into simple molecules that can be absorbed by the saprobiont by diffu...

Closed loop system Is the carbon cycle a closed loop system? FOR= carbon doesn't enter/leave the system, recycled no waste AGAINST= fossil fuels used up faster than replaced, sunlight energy enters/leaves the system

Water cycle The water cycle is the movement of H2O around the earth: sea water evaporates due to heat from the sun, condensates, turning into clouds, and finally, precipitates, falls down to earth.

About biogeochemical cycles notes
GoConqr OriginalUsing biogeochemical cycles notes
These notes offer different ways into the unit. Biogeochemical Cycles includes human impacts on the carbon, nitrogen and phosphorus cycles. Nitrogen Cycle introduces nitrogen fixation, while Carbon Cycle describes how carbon moves between the atmosphere and living things. The water cycle notes include processes such as evaporation and accumulation.
Plan a revision session
For a broad starting point, try Biogeochemical Cycles, then focus on one cycle. The nitrogen revision note is useful for returning to that topic, while a water cycle note can help you review its stages. Read a short section, put the process into your own words and check the note again for anything you missed.
When you want a change from reading, switch to flashcards on the unit page to revisit terms, or use a quiz to check what you remember. Pick a cycle and explore the notes that cover it.
Frequently asked questions
Which note should I start with?
For a broad view, start with Biogeochemical Cycles. It includes human impacts on the carbon, nitrogen and phosphorus cycles. If you want to focus on one topic instead, Nitrogen Cycle introduces nitrogen fixation, and Carbon Cycle describes carbon moving between the atmosphere and living things.
Are these notes free to use?
Yes. Every note listed here is free to open and study without an account. The notes were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
Which learners are these notes for?
The collection includes material for school students and primary pupils, as well as notes teachers can use when preparing lessons. Students revising nitrogen or carbon can choose a note focused on that cycle. Primary pupils can explore the notes on the water cycle.
