As CO2 is released into the atmosphere, it creates the greenhouse effect which is the trapping of heat on Earth?
What is the Cause? What is the Effect?
Cause: CO2 released into the atmosphere
Effect: greenhouse effect
100
What is global warming?
Increase in CO2 that traps heat from UV radiation; increasing global temperatures
100
What is the full equation for photosynthesis?

What reservoir do each of the resources belong to?
Oxygen
Rivers
Mountains
Humans
Oxygen -> atmosphere
Rivers -> hydrosphere
Mountains -> geosphere
Humans -> biosphere

We want to see if adding fertilizer to plants will help them grow taller.
What is the independent variable? What is the dependent variable?
IV: fertilizer
DV: plant growth

What type of energy only uses renewable resources?
Alternative Energy
200
What is the name of the process yeast perform to generate ATP (energy)? What are the other two products?
Fermentation (anaerobic respiration); alcohol and CO2
200
If a producer contains 590KJ of energy, how much energy is lost when transferred to the primary consumer level?
590-59= 531KJ
200
What is the product of combustion? What energy sources are typically combusted?
CO2, fossil fuels
300
The two graphs are examples of what would happen to Earth’s temperatures based on the amount of CO2 emissions in the future.
What is the cause? The effect?
Cause: increase in CO2 emissions
Effect: increased global temperatures

List 2 concerns about fossil fuels
Non renewable
Will run out eventually
Releases CO2
Pollutes the environment
300
If a plant is sitting in the dark, what is it doing?
Only cellular respiration
300
Who are the tertiary consumers?
Hawk and fox
300
Which process has nitrogen gas fixed into nitrites by bacteria?
Nitrogen fixation
400
Use to graph explain why the predator population begins to decline each time it does.
If there are too many predators, the prey population will start to decrease and the predators will eventually starve to death.
400
Why are fossil fuels nonrenewable resources?
They take millions of years to replenish and we’ll run out first.
400
If a plant is sitting in the dark explain what is happening to the oxygen and carbon dioxide levels in the room.
Oxygen is decreasing
Carbon dioxide is increasing
400
What is one food chain that makes the fox a tertiary consumer?
Grass 🡪 insect 🡪 vole 🡪 fox
Grass 🡪 insect 🡪 frog 🡪 fox
400
What is the amount of carbon in B?
6g/m2

The brain eating amoeba sits at the bottom of lakes and ponds. They are cysts (dormant) until the water gets warm (summer), then they hatch and can infect humans. Humans become infected if the amoeba in the water gets into their nose; this happens a lot with people falling while water skiing. If water temperatures continue to increase due to global warming, then the amoeba will be able to replicate more often and humans will be more susceptible to this parasite.
What is the cause? What is the effect?
Cause: increase in global temperatures
Effect: increase in active amoebas in the water that can infect humans

Long thought to be extinct, the mulgara, a small carnivorous marsupial, was recently rediscovered in Australia.
What could help ensure the natural survival of the mulgara population?
Limit human activities in the mulgara habitat
500
What is the purpose of photosynthesis? Cellular respiration?
Photo: convert light energy into chemical energy (glucose)
Cell. Resp.: convert chemical energy to ATP to do work
