carbon cycle key processes
photosynthesis,
cellular respiration
decomposition
fossilization
combustion
ocean uptake
nitrogen cycle
Nitrogen fixation
Nitrification
Assimilation
Ammonification
Denitrification
photosynthesis
processes by which plants and algae turn carbon dioxide gas and water into glucose and oxygen
cellular respiration
processes by which organisms make energy by converting glucose and oxygen into carbon dioxide and energy
decomposition
process by which decomposers break down dead organic matter, releasing carbon dioxide and organic compounds
fossilization
process where dead organisms can fossilize over thousands and millions of years to form fossil fuels
combustion
process of burning fossil fuels. releases carbon dioxide into the atmosphere
what are the three spheres?
lithosphere, hydrosphere, biosphere, and atmosphere
what are the layers of the earths atmosphere?
the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
(remember the acronym TSMTE)
