MYSTERY!
100
10% of energy is passed up a food pyramid. Energy that is not available to other organisms in a food web is energy that is:
Lost as heat
100
What is the equation for photosynthesis?
CoWS -> GO
100
What is the equation for Cellular Respiration?
GO -> COW!
100
What is labelled in "A"?
Phosopholipid Bilayer
100
What letter would you remove to turn ATP to ADP?
D
200
Some insects eat the nectar from hibiscus plants. The hibiscus plants make their own food using energy from light. The insects would be considered:
Heterotrophs
200
How are photosynthesis and cellular respiration opposite processes?
The inputs of one are the outputs of the other
200
What are the 3 stages of cellular respiration in order?
Glycolysis, Krebs Cycle, Electron Transport Chain
200
Cells need to bring in molecules that require moving the molecules across the cell membrane against the concentration gradient. How do these molecules get into the cell?
Active Transport
200
What would happen if there was a sudden increase in bird population?
Grasshopper population would decrease
300
What organism provides the energy for the secondary consumer?
Grasshoppers
300
An acorn that weighs one or two ounces can grow into an oak tree weighing as much as 3 to 4 tons! Where does all of that matter come from?
Carbon Dioxide & Water
300
If you are preparing to run a marathon, which macromolecule would be the best to consume to give you the right type of energy?
Carbohydrates
300
How would you describe this means of cell transport & how do you know that?
Active Transport, ATP is used
300
List out one food chain represented in this food web & show how much energy is passed between each
10% Rule
400
A flood covers a prairie and kills all the different organisms that live there. After some time, the waters dry up and some small life begins to appear. This would best describe a ___?
Secondary Succession
400
Stacks of tylakoids called what are suspended in the stroma?
Grana
400
Which type of molecule is formed from amino acids?
Proteins
400
What does hypertonic mean & what happens to cells in hypertonic solutions?
There is more water inside the cell than outside the cell; the cell will shrink
400
What can you deduce that "X" represents?
Producers
500
Why are there rarely more than three or four trophic levels in any food chain?
Not enough available energy to pass on
500
A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?
It will die- it needs Carbon Dioxide
500
Glucose is broken down into ___ during ___.
Pyruvate, Glycolysis
500
If your blood sugar drops, then glucagon causes the liver to release glucose back into the bloodstream. This is an example of a ___?
Negative Feedback Loop
500
what concept does this graph represent (hint: these are two organisms in the same niche)
Competitive Exclusion principle
600
"A" represents:
Carrying Capacity
600
Plants need carbon dioxide from their environment to produce glucose during which stage of photosynthesis?
Light Independent Stage
600
When muscles are exercised extensively in the absence of sufficient oxygen:
Aerobic respiration switches to anaerobic (lactic acid fermentation)
600
In aquatic ecosystems, the increased amount of carbon dioxide dissolving into the ocean cause an increase in the amount of carbonic acid, also known as ocean acidification. This increase in acidity causes the shells of some urchins to dissolve, in turn releasing more CO2, which causes more carbonic acid to be produced. What type of feedback loop does this represent?
Positive Feedback Loop
600
What type of organism is this diagram representing?
Decomposer
700
The amount of available nitrogen in an ecosystem can limit the amount of plants that can grow. This would be considered a(n)?
Density Independent Limiting Factor
700
Why does the rate of respiration decrease at high temperatures?
Enzymes become denatured
700
Where does anaerobic respiration occur
The cytoplasm
700
A cell that was in a hypotonic environment is moved to an environment of pure distilled water. What would you expect to happen?
Both are hypotonic, the cell would become isotonic
700
what non-gas molecule is represented by "i"?
Glucose
