Vocabulary
chemical substances that an organism needs to sustain life.
What are nutrients?
The processes of water going into the atmosphere and becoming clouds.
What is evaporation and condensation?
used by plants in the process of photosynthesis to make sugar and oxygen.
What is Carbon Dioxide (CO2)?
percentage of nitrogen in the atmosphere.
What is 78%?
phosphorus is not found in a free state in nature, instead is contained in these.
What are rocks and minerals?
nutrients whose supply hinders productivity.
What are limiting nutrient?
rain, snow, sleet, hail, and etc.
What is precipitation?
dead plants and animals give off huge amounts of carbon after death.
What is the process of decaying?
reason for nitrogen ending up in waterways.
What is humans’ fertilizers’ runoff?
nitrogen makes up important chemicals like this.
What is DNA?
classifications of cycles. (4)
What are Biological, Geological, Chemical/Physical, and Human Activity?
acidic water that is evaporated, condensed, and precipitated back to the ground, causing some damage to the surface of the earth.
What is acid rain?
reason for more CO2 being released into the atmosphere today than in the past.
What is the burning of fossil fuels?
higher organisms use nitrogen to make this.
What are proteins?
phosphorus moves between the soil and these, animals then eat them and the phosphorus is returned back to the ground through waste product.
What are plants?
cycles of nutrients being move around the biosphere. (4)
What are the Water, Carbon, Nitrogen, and Phosphorus Cycles?
Is water a renewable resource? (answer in statement)

What is transpiration?
photosynthesis equation.
What is CO2 + H2O = C6H12O6 + O2?
special bacteria that can directly use the nitrogen in the atmosphere and “fix” it for other organism’ benefit.
What are nitrogen-fixing bacteria?
too much phosphorus in water can lead to this, strangling other life forms in the water.
What is plant overgrowth?
