Content Objective: Describe how and how much carbon and methane cycles through the organisms and the environment.
Language Objective: Draw the carbon cycle and exploring how the movement of carbon effects the different carbon sinks.

Syllabus Details:
Skill: Construct a diagram of the carbon cycle.
Autotrophs convert carbon dioxide into carbohydrates and other carbon compounds
In aquatic ecosystems carbon is present as dissolved carbon dioxide and hydrogen carbonate ions
Carbon dioxide diffuses from the atmosphere or water into autotrophs
Carbon dioxide is produced by respiration and diffuse out of organisms into water or the atmosphere
Animals such as reef-building corals and Mollusca have hard parts that are composed of calcium carbonate and can become fossilized in limestone
Peat forms when organic matter is not fully decomposed because of acidic and/or anaerobic conditions in waterlogged soils
Carbon dioxide is produced by combustion of biomass and fossilized organic matter
Partially decomposed organic matter from past geological eras was converted either into coal or into oil and gas that accumulate in porous rocks
Application: Estimation of carbon fluxes due to processes in the carbon cycle.
Methane is produced from organic matter in anaerobic conditions by methanogenic archaeans and some diffuses into the atmosphere or accumulates in the ground
Methane is oxidized to carbon dioxide and water in the atmosphere
