Water Cycle
Rain, snow, sleet, and hail are all examples of this part of the water cycle
What is precipitation?
The process that plants use sunlight, carbon dioxide, and water to make food.
What is photosynthesis?
What process converts nitrogen gas from the atmosphere into ammonia?
What is nitrogen fixation?
This nutrient cycles through the ecosystem by evaporation, condensation, precipitation, and collection/accumulation.
What is the water cycle?
The process of liquid water turning into a gaseous form
What is evaporation?
Burning of a substance that releases carbon dioxide into the atmosphere.
What is combustion?
Nitrates are converted back to N2 (nitrogen gas) by this kind of bacteria
What is denitrifying bacteria?
This nutrient cycles through ecosystems by photosynthesis, cellular respiration and decomposition.
What is the carbon cycle?
When warm, moist air meets cooler air, this part of the water cycle takes place to form a cloud
What is condensation?
The breakdown of substances into simpler molecules.
What process converts ammonia into nitrate?
What is nitrification?
Bacteria and lightening play a major role in this cycle.
What is the nitrogen cycle?
Storm water that picks up pollutants and then flows into a body of water is called __________.
What is runoff?
Exchange of oxygen and carbon dioxide between living cells and their environment
What is respiration?
What process converts nitrate BACK into nitrogen gas?
What is denitrification?
Changes in this cycle are primarily responsible for climate change (global warming)
What is the carbon cycle?
Process by which plants give off water vapor from their leaves
What is transpiration?
Materials stored in carbon sinks (long-term storage)
What is fossil fuels?
True or False: Decomposition will turn dead nitrogen-containing plants and animals back into NITROGEN GAS.
What is false?
Fertilizers can cause an increase in the nutrients in this cycle.
