Daily Double Daily Double 10 Daily Double Which would you expect to find more of in this ecosystem, toads or snakes? Why? Daily Double

5 Toads: There is more energy available and therefore more biomass at the lower levels of an ecological pyramid. More primary consumers than secondary, etc.

6 In which level(s) of the pyramid below would you find Carnivores Primary consumers

7 Carnivores: Levels 3 and 4 Primary consumers: Level 2 only

8 If the plants in this community absorbed 300,000 kilocalories of energy, how much energy would you expect to find in each level as you move up the food chain?

12 Define the term Population.

13 Members of a species living in the same place at the same time. The individuals must be interdependent.

22 Who is this?

23 Who is Matt Cassel?

14 Draw a graph showing a population growing under ideal conditions, with unlimited resources.

15 Exponential Growth

16 Would you expect the size of this population to change in the future? Explain.

17 No. The graph shows a stable population with equal percentages of people in pre- reproductive and reproductive ages.

18 A What is happening at the point on the graph labeled “A”? Your answer must include vocabulary terms.

19 The population has reached its carrying capacity because of a limiting factor. The population will not exceed this number of individuals.

20 What are limiting factors? Give 2 examples of limiting factors for a population of fish in the ocean and 2 examples of factors that may be limiting for the global population of humans.

21 Fish: food, territory, mates Humans: Food, space, water

26 What type of symbiosis is shown in this picture?

27 Mutualism

28 List the letters of the ponds from youngest to oldest.

29 BCAD

30 Define commensalism. Give an example.

31 Symbiotic relationship in which one organism benefits, the other is unaffected. Ex: Barnacles on a whale.

32 Which nutrient cycle is shown below? Describe what is happening at #s 2, 3, and 4.

33 The water cycle. 2 – condensation 3 – evaporation 4 – precipitation

DAILY DOUBLE DAILY DOUBLE 36 Explain how carbon cycles through the environment. Name 2 processes involved in the cycling of carbon. DAILY DOUBLE DAILY DOUBLE

37 Photosynthesis: Plants take CO2 from the air and build sugars. Cellular Respiration: Organisms break the sugars down to release energy and CO2.

38 Explain the difference between primary and secondary succession.

39 Primary succession begins on bare rock; Secondary begins on soil.

40 Identify the organisms functioning at each letter in the diagram of the nitrogen cycle.

41

42 How is a population different from a community?

43 Population is organisms of only one species living in an area. Community is organisms from different, interdependent species.

44 All the organisms living in and on a decaying log can best be described as a _____________.

45 Community.

46 Choose 1 biome and explain it’s unique characteristics. (How is this biome different from others?)

47 Answers vary. Include rainfall, climate, organisms, etc.

48 What are biotic factors? What are abiotic factors? Give 2 examples of each.

49 Biotic = living. Plants, animals, decomposers. Abiotic = nonliving. Climate, precipitation, water.

50 Give a detailed procedure for estimating population size. Why is this a useful strategy?

51 Mark and recapture: Mark a few organisms, release them. Capture and release several times, keeping track of how many organisms are marked. Random Sampling: Place a grid on the land, randomly chose a few squares in the grid. Count organisms in those squares.

How are nitrogen-fixing bacteria beneficial to plants? 52 FINAL JEOPARDY How are nitrogen-fixing bacteria beneficial to plants?

53 Take nitrogen from the air (N2) and build it into useable molecules (ammonia, nitrates and nitrites). These are needed by the plant to make proteins.
