  1. Ecology Review

  2. What is Ecology? -the study of the relationships between living things and their environment

  3. Where an organism lives is its _ _ _ _ _ _ _. h a b i t a t

  4. The arrow on the right of this picture represents ********** *************. biological magnification

  5. If conditions are such that all the members of a population survive andreproduce the population is growing at its ______ _________. biotic potential

  6. Which of the following describe the trophic level of a white oak tree? • Producer • Fruits are eaten by deer • Flowers in late April • Ms. Metter’s favorite tree • Found in deciduous forests A.

  7. Which of the following describe the habitat of a white oak tree? • Producer • Fruits are eaten by deer • Flowers in late April • Ms. Metter’s favorite tree • Found in deciduous forests E.

  8. Which of the following describe the nicheof a white oak tree? • Producer • Fruits are eaten by deer • Flowers in late April • Ms. Metter’s favorite tree • Found in deciduous forests 1,2,3,5

  9. What are the two factors that increase population size? natality immigration

  10. web This drawing represents a food _______.

  11. Name two organisms that are competitors in this web. gull & crab -for mussels

  12. No! no two organisms can have the same niche. Do the two competitors have the exact same niche? Explain.

  13. Which color on this graph shows exponential growth? where the red and blue overlap

  14. What on this graph shows carrying capacity? K1 & K2

  15. If two organisms had the exact same niche, one would out-compete the other. This is known as competitive exclusion

  16. Go to the board and draw a diagram that shows the movement of energy through an ecosystem. check your packet

  17. All the organisms of one species in an area = a __________. population

  18. Go to the board and draw a diagram that shows the movement of matter through an ecosystem. check your packet

  19. Which of these communities is the most stable? Why? One on right – More diversity

  20. Which of these organisms would you expect to have the greatest accumulation of mercury? WHY? Whale – biological magnification

  21. Symbiotic relationship in which BOTH organisms BENEFIT. mutualism

  22. What are the two factors that decrease population size? Emigration Mortality

  23. What type of curve is this? Exponential growth / Biotic potential

  24. What is nitrogen fixation? -process used by nitrogen fixing bacteria to take N2 gas out of the air and put it in a usable form

  25. A type of relationship that HARMSBOTH organisms. Competition = not symbiotic!

  26. Name one Omnivore in this Community. none

  27. grasshopper or cricket – herbivore Name one Primary Consumer in this Community. What is another name for a primary consumer?

  28. Define MATTER. anything made of atoms, has mass, takes up space

  29. What type of curve is this? logistic growth curve

  30. ALL the organisms in an area = a _________. community

  31. What are the two types of DECOMPOSERS? bacteria, fungi

  32. Food provides consumers with both __________ and __________. Energy Matter

  33. Describe a predator-prey relationship in this community. hawk – shrew, snake – frog, etc

  34. Any close relationship between two or more organisms is know as _ _ _ _ _ _ _ _ _ s y m b i o s i s

  35. What an organism EATSdetermines its _ _ _ _ _ _ _ _ _ _ _ _ T r o p h i c L e v e l

  36. L.F. C.C. B.P. On this curve label the carrying capacity, biotic potential and limiting factors.

  37. What type of symbiotic relationship exists between the shark and remora? Commensalism – shark is not helped or harmed, remora is helped (gets food from the messy eater shark)

  38. hawk If there were 1,800 kg of tadpole in this community, how many kg of secondary consumer would you expect? sunfish tadpole duckweed 180 kg of sunfish

  39. If the amount of duckweed was severely reduced in this community, which organism would be most affected? hawk sunfish tadpole duckweed Hawk

  40. If the average hawk is 1 kg, how many hawks would you expect this ecosystem to support? Explain. hawk sunfish tadpole 180 duckweed 1800 ONE! You can’t have .8 of a hawk

  41. What are tworesources the hickory and bur oak trees in my back yard are competing for? Water, Light, Nutrients

  42. The sun is the DIRECT form of energy for _ _ _ _ _ _ _ _ _. p r o d u c e r s

  43. What FORM of energy is directly used by animals? chemical

  44. List three ways that energy is lost from a food chain. cellular respiration, growth, repair, reproduction, active transport, etc

  45. #19. Which of these best shows the flow of energy in an ecosystem? Explain 2nd arrow, energy is not cycled and it decreases as you go through the food chain.

  46. #19. Which of these best shows the flow of matter in an ecosystem? Explain 3rd arrow, matter is cycled and it is not lost.

  47. Identify three factors other than habitat and food that animals might compete for. water, mates, nesting materials, shelter

  48. Less energy is lost if organisms eat _ _ _ _ _ on the food chain. lower

  49. Which population graph shows homeostasis? homeostasis

  50. What does the competitive exclusion principle state? No two species can occupy the exact same niche at the exact same time.
