Carbon Cycle Summary

Flashcards covering key concepts related to the carbon cycle, including definitions and functions of processes within it.

Law of Conservation of Matter

States that matter cannot be created or destroyed; it applies to the carbon cycle by ensuring that carbon atoms are recycled through various processes such as photosynthesis and respiration.

Photosynthesis

A process used by plants and other organisms to convert light energy, usually from the sun, into chemical energy in the form of glucose, playing a critical role in the carbon cycle.

Cellular Respiration

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water, balancing photosynthesis in the carbon cycle.

Carbon Sinks

Natural reservoirs that store carbon-containing chemical compounds for an indefinite period, such as forests and oceans.

Carbon Sources

Processes or activities that release carbon into the atmosphere, such as fossil fuel combustion and animal respiration.

Atmospheric Carbon Dioxide Concentration

The amount of CO₂ present in the atmosphere, usually measured in parts per million (ppm), which fluctuates seasonally due to natural processes.

Fluctuations in CO₂ Data

Seasonal variations in atmospheric carbon dioxide levels caused by the cyclic patterns of plant photosynthesis and respiration throughout the year.

Global Carbon Dioxide Emissions

The total amount of carbon dioxide produced through human activities, particularly fossil fuel combustion, measured over time.
