1 Respiration & Decomposition (2 biochemical processes)
Two processes where carbon is ADDED to the atmosphere

2 Also known as cellular respiration
All living things need nutrition & oxidise this nutrition to release energy

3 Food Chains Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Primary Producer Primary Consumer Secondary Consumer Tertiary Consumer

4 Cellular Respiration Food Oxygen Carbon dioxide Water C6H12O6 6O2 6CO2
This is the chemical reaction that takes place inside the cells of plants and animals

5 Plants & animals release waste products & eventually die!
Excretion & Death Plants & animals release waste products & eventually die!

6 Excretion & Death EXCRETION OR WASTE PRODUCTS
(CARBON WILL BE IN THESE PRODUCTS) Soil / bottom of ocean. CO2 from respiration Pooh & Pee (or an organisms equivalent) Fart – methane gas Plant leaves that fall to the ground

7 Decomposition This is a process where micro-organisms breakdown dead organisms & the waste products from organisms

8 Decomposition DEAD ORGANISMS & THEIR EXCRETION OR WASTE (Fecal) PRODUCTS (CARBON WILL BE IN THESE MATERIALS) This non-living material (containing carbon) is a source of nutrients for the bacteria & Fungi. They decompose the material (a process commonly known as rotting) and produce carbon dioxide gas as their own waste product from respiration. Detritus is a term given to rotting material found in soil and sediments RIP

9 Microbes Re-Cycling Carbon
Soil bacteria If it wasn’t for microbes, then the carbon stored in the dead bodies and faecal material of organisms would remain ‘locked-up’. Microbes are part of the fast carbon cycle – recycling carbon back into other components of the system. Soil fungi

10 ADDITION Through respiration& decomposition, carbon dioxide & methane gas can be added to the atmosphere Plants & Animals are a temporary SINK for carbon compounds but eventually give them up to the atmosphere, soil or aquatic system that they are living in.
