Intro Vocabulary
Carbon = an element that is found in all living/dead things
Fossil fuels = energy sources formed from the fossils of dead organisms Fossil fuels are made of carbon Examples: oil, coal, natural gas
Key Point #1: Carbon is found in different forms and different sourcesSources of carbon– Plants– Animals– Soil– Fossil fuels– Dead things– Atmosphere
PhotosynthesisRespirationDecompositionCombustion (fossil fuel burning)
Gas exchange
Five steps of the carbon cycle
AProcess: Cellular respirationIllustration Description: Arrow points from plants to atmosphere
Definition: plants and animals break down organic carbon to CO2
Money Analogy: returning money (CO2) to the bank
BProcess: PhotosynthesisIllustration Description: Arrow points from atmosphere to plants
Definition: plants convert CO2 into glucose (sugar)
Money Analogy: taking money out of the bank as dollars
CProcess: CombustionIllustration Description: from factory to atmosphere
Definition: burning fossil fuels releases CO2
Money Analogy: returning money (CO2) to the bank
DProcess: Gas exchangeIllustration Description: arrows between water and atmosphere
Definition: CO2 dissolves in and out of water
Money Analogy: money in and out of bank
EProcess: DecompositionIllustration Description: dead animals to underground
Definition: carbon stored as fossil fuels after things die
Money Analogy: money hidden under the bed
What step of the carbon cycle???
Involves plants removing CO2 from the atmosphere?
Involves plants and animals releasing CO2 into the atmosphere?
Involves a human activity releasing CO2 into the atmosphere?
Adds and releases CO2 into the atmosphere at the same time?
Take the carbon cycle a step farther…
