18. Define Ecological Succession:
19. What are the two types of Ecological Succession?
1. ___________________________________________
2. ___________________________________________
20. Primary Succession takes place on exposed, bare rock which lacks a ____________________.
21. Usually follows a _________________________________ or ____________________________________________.
22. Primary succession begins with a _________________________ species such as
____________________________________________.
23. Secondary Succession takes place in a newly cleared area, ________________________ remains.
24. Usually follows a ______________________________ or ______________________________________________.
25. Define Competition:
26. Define Predation:
27. Define Symbiosis:

38. Define Food Webs:
39. Food webs are made up of simple ______________________________________.
40. Define Food Chains:
41. At each tropic level ________________% of energy is lost. Which means ________% of energy is passed on.
42. What group has the most energy available? Where does this energy come from?
43. Top carnivores have less available energy . What is the size of their population?
44. Fill-in the Energy Pyramid below
