The Carbon Cycle

ammonium ions

SOme ________ and amino acids are converted into the vascular tissues of the hosts plants and roots.

Ammonification →

________ Bacteria and fungi decompose dead organisms and animal products leaving Nitrogen into the plants.

Rhizobium

________ → Symbiotic relationship with legumes, inhibited by oxygen, plant produces leghaemoglobin so N2 fixation can happen.

Reaction

________ is catalysed by nitrogenase enzymes, will not work under oxidation.

Denitrification → Anaerobic bacteria

________ convert nitrates om the soil to nitrogen in reduction reactions.

Photosynthesis

________- Fixation of atmospheric CO2 by plants using sunlight energy and its conversion to carbohydrates, releasing oxygen as its product.

Combustion

________- Release of C02 when organic substances are burned.

Respiration

________- Release of energy from high energy substances releasing CO2 into the atmosphere.

Organic compounds

Feeding- ________ passed along food chains.

Sedimentation

________- Deposition of skeletons of marine animals on sea bed.

Nitrogenase

________ is inhibited by oxygen so it is surrounded by leghaemoglobin.

Methane

________ → Decomposition, anaerobic respiration, Marshes, intensive Farming, Rice Fields, Landfill sites.

protein synthesis

The uptakes are linked with ________ of nucleic acids.

CO2

Ploughing increases decomposition (________)

Combustion of fossil fuels

________ has released CO2.

Fossilisation

________- Incomplete decomposition leading to the formation of fossil fuels.

Nitrification → aerobic bacteria

________ add nitrites and nitrates to the soil in oxidation reaction.

Climate Pattern

Change in ________ → Hurricanes, Wind patterns, Precipitation.

Carbon Resovoirs

________- Places where carbon atoms exist, Atmosphere, living things, organic matter, fossil fuels, rocks, oceans.

Nitrogen Fixaton → Nitrogen

________ fixing bacteria in the soil convert Nitrogen gas into ammonium ions and in symbiotic bacteria, organic acids and amino acids.

Nitrogen

________ is taken up by roots as ammonium and nitrate ions.

Decomposition

________- Breakdown of organic matter, releasing CO2 in anaerobic conditions, CH4 in anaerobic conditions.

Ammonification →

________ Bacteria and fungi.
