Sustainability is

• the process of maintaining resources so they are not depleted or permanently damaged

• the ability to use resources faster than they are renewed

• they ability to save resources for years and years

• the process of using resources for one's own benefit without regard for others

What is a negative consequence of overgrazing?

• The land can turn into a desert (desertification) and can no longer be used for feeding or agriculture.

• The cows become overweight.

• Vegetation becomes overfertilized and grows uncontrollably.

• Vegetation becomes plentiful and lasts for decades.

According to the diagram, the movement of phosphorus between biological organisms and soil is in a steady state in an undisturbed system. Which of the following best explains the reason for this steady movement?

• Phosphorus is taken up by plants during photosynthesis to create carbohydrates.

• A decrease in buffer zones prevents phosphorus runoff in waterways.

• There is a rapid influx of phosphorus from the weathering of rocks.

• Readily available organic phosphorus in the soil is assimilated by plants.

Which of the following best describes gross primary productivity in an ecosystem?

• Gross primary productivity is the total amount of energy captured by producers plus the energy used by consumers over time.

• Gross primary productivity is the total amount of energy captured by producers minus the energy that producers respire over time.

• Gross primary productivity is the total amount of energy lost as heat during energy transfer between trophic levels.

• Gross primary productivity is the total amount of solar energy captured by producers through photosynthesis over time.
