4. What is the Second Law of Thermodynamics? (1 mark) The entropy of the universe always increases. 5. All energy is eventually converted into what form of energy? (1 mark) All energy is eventually converted into heat. 6. Organisms are not closed systems because they use two things, which are: (2 marks) Energy and Matter.
7. The producers in a food chain are called what? (1 mark) Autotrophs 8. Give an example of potential energy. (1 mark) A tank of gasoline 9. Give an example of kinetic energy. (1 mark) Burning gasoline 10. Energy arrives from the Sun , passes through autotrophs to herbivores to carnivores and omnivores to saprophytes , and then 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) Releases energy (from the bonds holding the atoms of large molecules together). 13. Give the definition for: anabolism. (1 mark) Requires energy (to form new atomic bonds within molecules). 14. Give the definition for: metabolism. (1 mark) The totality of an organism's chemical processes, consisting of catabolic and anabolic pathways. 15. Give the definition for: chemical reaction. (1 mark) A process leading to chemical changes in matter; involves the making and/or breaking of chemical bonds. 16. Give the definition for: bond energy. (1 mark)
The quantity of energy that must be absorbed to break a particular kind of chemical bond; equal to the quantity of energy the bond releases when it forms 17. Catabolizing + Anabolizing = Metabolizing (1 mark)
