Autotrophs 8. Give an example of potential energy. (1 mark) The Energy stored in carbohydrates. 9. Give an example of kinetic energy. (1 mark) Burning gasoline. 10. Energy arrives from ( the son ), passes through ( autotrophs to herbivores to carnivores and omnivores to saprophytes ), and dissipates into ( the environment and the universe ), as heat. (4 marks) 11. Nutrients are passed from one organism to another in closed loops called ( biogeochemical cycles ). (1 mark) 12. Give the definition for: catabolism. (1 mark) Catabolism releases energy (from the bonds holding the atoms of large molecules together). 13. Give the definition for: anabolism. (1 mark) Anabolism requires energy (to form new atomic bonds within molecules). 14. Give the definition for: metabolism. (1 mark) All of the chemical reactions (the catabolism and the anabolism) within a cell or within a whole organism. 15. Give the definition for: chemical reaction. (1 mark) Rearranging/combining/breaking apart molecules. 16. Give the definition for: bond energy. (1 mark) The energy that holds atoms together into molecules. 17. Catabolizing + Anabolizing = ( met abolizing ) (1 mark)
