69% of all freshwater is trapped in ice caps and glaciers.
Transpiration through the leaves of plants.

- 15. Multiple Choice
As CO2 concentration increases in this graph, how is average global temperature affected?
As CO2 concentration increases, average global temperature increases.
As CO2 concentration increases, average global temperature decreases.
As CO2 concentration increases, global temperature stays the same.
CO2 concentration and average global temperature have no relationship.
- 16. Multiple Choice
Based on this graph, you can infer that
CO2 absorbs heat which makes global temperature rise as CO2 concentration increases.
CO2 levels do not affect the global temperature because the graph shows no correlation between the two.
Global temperature is going to increase so much that the ice caps and glaciers will melt in a few years.
Global temperature is increasing which means CO2 concentration will decrease in the next few years.
- 17. Multiple Choice
Which of the following explains the long term portion of the phosphorus cycle?
Phosphorus is stored in rocks, and it is slowly recycled back into the ecosystem through weathering and erosion.
Phosphorus is constantly cycled through the food chain starting at the producer level and working its way to the apex predator.
Phosphorus does not have a long term portion.
Phosphorus cannot be recycled and reused because it is a nonrenewable resource.
- 18. Multiple Choice
If a farmer uses an excessive amount of fertilizer and this fertilizer washes into a nearby lake in runoff, what is likely to happen in this area?
The plant life will grow exponentially, and many of the fish living in this area will die.
The plant life will be destroyed, and many of the fish in this area will die due to a lack of food.
The fish in this area will multiply exponentially, and they will destroy the plant life.
Fertilizer will not affect the area because it only affects the growth of plants that grow on land.
- 19. Multiple Choice
