Transcript Cycles of Matter
Biogeochemical Cycles
Elements, compounds and
other forms of matter are
passed from one organism to
another and from one part of
the biosphere to another.
The Phosphorus Cycle
Phosphorus in the biosphere
cycles among the land,
ocean, sediment and living
organisms
The Carbon Cycle
4 MAIN PROCESSES MOVE CARBON
1. Biological processes- photosynthesis,
respiration and decomposition.
2. Burial and decomposition of dead
organisms and their conversion under
pressure (fossil fuels).
The Carbon Cycle
3. Geochemical processeserosion and volcanic activity (
release CO2).
4. Mining, cutting and burning
forests (burn fossil fuels).
The Nitrogen Cycle
The atmosphere is the main
reservoir of nitrogen, it also
cycles through the soil and
tissues of living organisms.
The Water Cycle
Water constantly moving between
the atmosphere and Earth.
Please be able to label the water
cycle.
