-
Carbon
- element
- found in all organisms=organic material
- found in proteins, lipids, carbohydrates, and vitamins=organic compounds
- CO2 is not an organic substance
-
Word equation of Photosynthesis
Carbon Dioxide + Water --> Sunlight + Chlorophyll --> Glucose + Oxygen
-
Chemical Equation of Photosynthesis
6CO2 + 6H2O -> Sunlight+Chlorophyll -> C6H12O6 + 6O2
-
Glucose
Food/Chemical energy
-
What can do photosynthesis?
Autotrophs/Producers
-
What does photosynthesis do?
Nutrition
-
Respiration
break down of glucose to release energy
-
Word Equation of Respiration
oxygen + glucose --> carbon dioxide + water + energy
-
Chemical Equation of Respiration
6O2 + C6H12O6 --> 6CO2 +6H2O + energy
-
Decomposition
dead organic matter is broken down by organisms called decomposers (bacteria + fungi)
-
How is glucose is broken down?
By the decomposers in the process of respiration.
-
Fossilisation
dead organic matter can't decompose (lack of O2) over millions of years it forms into fossil fuels (oil, coal, gas)
-
Combustion
burning of fossil fuels
-
What do fossil fuels contain?
Carbon
-
Word Equation of Combustion
(fossil) fuel + oxygen --> carbon dioxide + water + energy
-
Nutrition
taking in food (containing C = glucose, sucrose, carbohydrates, fats, proteins)
-
organic
- living/dead organisms
- contains carbon
