5. All energy is eventually converted into what form of energy? (1 mark) All energy is eventually converted into heat form of energy.
6. Organisms are not closed systems because they use two things, which are: (2 marks) Matter and Energy 7. The producers in a food chain are called what? (1 mark) The producers in a food chain are called autotrophs. 8. Give an example of potential energy. (1 mark) An example of potential energy is tank of gas waiting to be burnt. 9. Give an example of kinetic energy. (1 mark) An example of kinetic energy is burning of gasoline. 10. Energy arrives from sun , passes through autotrophs to herbivores to carnivores and omnivores to saprophytes , and dissipates into environment and the universe , as heat. (4 marks) 11. Nutrients are passed from one organism to another in closed loops called cycles (1 mark) 12. Give the definition for: catabolism. (1 mark) Catabolism releases energy to 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) Metabolism is the set of chemical reactions in organisms. 15. Give the definition for: chemical reaction. (1 mark)
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. 16. Give the definition for: bond energy. (1 mark) Bond Energy is 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)
