Question

) QUESTION 2: Grass is the "starting point" of this food chain. What role does it play? (1 point)
Primary consumer
Producer
Decomposer
Secondary consumer
C) QUESTION 3: What overall pattern do you see in the consumer populations after the grass was cut? (1 point)
They increased
They decreased
They stayed the same
Only hawks decreased
D) QUESTION 4: Which population was directly affected first when grass was reduced? (1 point)
Grasshoppers
Frogs
Snakes
Hawks
E) QUESTION 5: In this food chain, which organism is a secondary consumer? (1 point)
Grass
Grasshopper
Frog
Hawk
F) QUESTION 6: If you wanted to clearly show how populations changed before and after, which type of graph would
you pick? (1 point)
Pie chart
Bar graph
Line graph
Histogram
G) QUESTION 7: What would most likely happen to hawks if grass kept decreasing? (1 point)
Their population would increase
Their population would decrease
Their population would stay the same
They'd switch to eating grass
H) QUESTION 8: The arrows in a food web always point to show the flow of: (1 point)
Matter
Energy
Both matter and energy
Population size
I) QUESTION 9: In this experiment, what did you (the scientists) change on purpose? (This would be your independent
variable) (1 point)
Grass amount
Number of grasshoppers
Snake population
Hawk population
J) QUESTION 10: What was measured or observed as a result? (1 point)
Grass amount
Consumer population sizes
Amount of sunlight
Type of organism
K) QUESTION 11: What would most likely happen to grasshopper numbers if you added fertilizer and helped the
grass grow more? (1 point)
Increase
Decrease
Stay the same
Decrease then increase
L) QUESTION 12: Why are decomposers important in this system, even though they aren't on the table? (1 point)
They pass energy directly to hawks
They recycle nutrients back into the soil
They make grass grow instantly
They increase frog populations
M) QUESTION 13: Why did the snake population go down when grass was reduced? (1 point)
Snakes eat grass
Snakes had fewer frogs to eat
Snakes were eaten only by hawks
Snakes turned into hawks
N) QUESTION 14: What kind of relationships do snakes and frogs have? (1 point)
Mutualism
Predator-prey (predation)
Competition
Commensalism
O) QUESTION 15: What's the BIG takeaway from this experiment? (1 point)
Energy decreases as you move up the food chain
Grass doesn't matter in a food web
Hawks and snakes help grass grow
Removing grass increases consumer populations
