a series of events that occur in a regular repeating pattern; examples of cycles will vary
Cycle
the exchange of matter through the biosphere, which involves living organisms, geological processes, and chemical processes
Biogeochemical Cycle
The carbon cycle is made of several processes, including and
Photosynthesis and Respiration
Name the Cycle
1. underground,in the atmosphere, and on Earth’s surface, basis of life for all living things KEY WORDS evaporating, water vapor, precipitation, transpiration
2. in the atmosphere; in plants, to produce proteins; in chemical fertilizers KEY WORDS nitrogen fixation, nitrates, decomposers, ammonia, denitrification
1. Water
2. Nitrogen
1. in all living things, in the atmosphere, make up molecules such as carbon dioxide and sugar KEY WORDS photosynthesis, cellular respiration, fossil fuel, calcium carbonate
2. cell compounds; in Earth’s crust, essential for growth and development of organisms KEY WORDS decomposers, weathering, erosion, phosphates
1. Carbon
2. Phosphorus
anything that takes up space and has mass
Matter
a layer of gases surrounding a planet or other celestial body, held in place by gravity
Atmosphere
get nitrogen by eating plants or animals that contain nitrogen.
Consumers
Put in order
Through condensation, water in the air changes from a gas to tiny droplets of liquid.
Groundwater and runoff from land surfaces flow into rivers, lakes, and oceans.
Through evaporation, water changes from a liquid to a gas that becomes part of the air.
Water returns to Earth as rain or snow through the process of precipitation.

The nitrogen is captured and converted into a form that is usable by plants in a process called
Nitrogen Fixation
a process in which some soil bacteria convert fixed nitrogen compounds back into nitrogen gas, which returns to the atmosphere
Denitrification
the biological process where plants, algae, and cyanobacteria convert light energy into chemical energy
Photosynthesis
This compound is changed by organisms in the soil into other nitrogen compounds that can be used by plants. Finally, some soil bacteria convert nitrogen compounds into nitrogen gas, which returns to the atmosphere in a process called
Denitrification
through the environment due to the flow of energy in ecosystems.
Cycles
break down organic matter found in organisms into
Decomposers, Ammonia
the conversion of nitrogen gas to ammonium
Nitrogen Fixation
a chemical element with the symbol C and atomic number 6. It is a tetravalent nonmetal, meaning its atoms can form up to four covalent bonds
Carbon
is a part of all organic compounds, which make up living things.
Carbon
Nitrogen enters the food web when absorb nitrogen compounds from the soil and use them to make proteins.
Plants
Nitrogen is a nutrient that organisms need to produce
Proteins
a chemical substance that an organism must obtain from its environment to sustain life and to undergo life processes
Nutrient
inorganic chemical compound of nitrogen and hydrogen with the formula NH₃
Ammonia
Plants and animals cannot use the nitrogen that makes up a large percentage of the
Atmosphere
During these processes, carbon moves between its major reservoirs.
These major reservoirs include the , the
, and
Water, Atmosphere, Living Organisms
Nitrogen is returned to the soil when animals or when organisms die and
