Biogeochemical and Global Warming Practice quiz

transpiration is

• Evaporation from leaf stomata

• Precipitation from leaf stomata

• Whatsamatta with you?

• Condensation from leaf stomata

All but one are effects of deforestation:

• Soil Erosion/increased runoff

• Decreased Biodiversity/loss of habitat

• Increased atmospheric CO2 / Decreased Ocean pH

• Eutrophication/ algal blooms

Less ground water and less precipitation are probably due to what's known as:

• A drought

• A famine

• Nitrogen Fixing bacteria

• Urbanization

The biogeochemical/nutrient cycle affected by ammonia fertilizers:

• Hydrologic (water)

• Carbon

• Nitrogen

• Phosphorus

What organism is responsible for “fixing” nitrogen in the nitrogen cycle?

• Plants

• Animals

• Humans

• Bacteria

The atmosphere plays a significant role on most cycles except for one that we learned about. Which cycle does not incle the atmosphere as a significant part of its cycle?

• CaRbOn

• WaTeR

• nItRoGeN

• PhOsPhOrUs

what would an over-enrichment of phosphorus cause in a body of water?

• Algal bloom -> Eutrophication

• THE DEATH OF ALL THINGS NOT BEARING THE NAME STEVE

• Increase in carbon dioxide and global warming

• El Nino and La Nina

What is the MAIN thing humans do that has a significant effect on the atmosphere's greenhouse gas?

• Commit Cellular Respiration

• Urbanization

• Ocean Acidification

• Combustion of (burning) Fossil Fuels

Why is ozone one greenhouse gas we want?

• It's a shield against the sun's UV rays

• There's a hole in it

• It's...smelly.

• There is less of it than CO2

What are the positive affects of higher atmospheric carbon dioxide levels?

• Higher Sea levels

• More acidic ocean water

• Plants have more CO2 to use for photosynthesis

• Humans can breathe more.
