22
Difference between abiotic & biotic factors
$100 Question – Energy Difference between abiotic & biotic factors
23
$100 Answer – Energy Abiotic – non-living factors (soil, water, etc)
Biotic – living factors (plants, animals, etc)
24
Names of the 3 ecological pyramids
$200 Question – Energy Names of the 3 ecological pyramids
25
$200 Answer – Energy Pyramid of energy Pyramid of biomass
Pyramid of numbers
26
Make a simple food web including:
$300 Question – Energy Make a simple food web including: Snake Hawk Grasshopper Mice Chickadee Plants (grass)
27
Chickadee Mice Grasshopper
$300 Answer – Energy Snake Hawk Chickadee Mice Grasshopper Plants (grass)
28
$400 Question – Energy Difference between primary & secondary succession. Example of when each occurs.
29
$400 Answer – Energy Primary – when no soil; example: after volcanic eruption Secondary – soil remains as do the seeds/spores within it; example: forest fire
30
Describe primary succession
$500 Question – Energy Describe primary succession
31
$500 Answer – Energy 1. Lichens – acids create soil
2. Simple plants (mosses/ferns) can grow on new soil 3. Simple plants die & add organic matter to soil; soil layer thickens 4. Grasses & wildflowers establish themselves 5. Meadows die & small shrubs/trees can now grow 6. Larger trees & other climax species come in
32
$100 Question – Population
Explain density independent limiting factors & give example
33
$100 Answer – Population Population growth regardless of size are
affected; ex) drought
34
$200 Question – Population
Explain density dependent limiting factors
35
$200 Answer – Population Most noticable when populations are large;
The larger the population, the more they are affected by these limiting factors ex) competition, predation, parasitism, crowding/stress
36
$300 Question – Population
Define carrying capacity
37
$300 Answer – Population Number of organisms of a particular species that can be supported by the environment
38
$400 Question – Population
Explain an exponential growth curve
39
Will continue to grow until something stops it
$400 Answer – Population Conditions are ideal Growth begins slowly but increases rapidly as more organisms join the population Will continue to grow until something stops it
40
$500 Question – Population
Draw & describe a logistic growth curve
41
$500 Answer – Population To start, population grows slowly
Population grows rapidly Population growth slows down (but is still growing) Population growth slows down even more as it appr0aches carrying capacity Population reaches a steady state
42
$100 Question – Interactions
Difference between interspecific & intraspecific competition
43
$100 Answer – Interactions
Intraspecific – between members of the same species Interspecific – between members of different species
44
$200 Question – Interactions
Draw a predator-prey cyclic growth curve
45
$200 Answer – Interactions
46
$300 Question – Interactions
List the three types of symbiosis
47
$300 Answer – Interactions
Commensalism Mutualism Parasitism
48
$400 Question – Interactions
Explain parasitism & give example
49
$400 Answer – Interactions
Relationship in which one species benefits & the other is harmed; example: tapeworms
50
$500 Question – Interactions
Explain the difference between commensalism & mutualism. Give examples.
51
$500 Answer – Interactions
Mutualism – relationship in which both species benefit (crocodile & plover) Commensalism – relationship in which one species benefits & other is unaffected (mite & dragonfly)
52
Final Jeopardy Define ecology
53
Final Jeopardy Answer Study of organisms & their interactions with each other and their environment
