The process which plants use CO2 to make oxygen and sugar.
What is photosynthesis?
Too much phosphorus in water can lead to this.
What is plant overgrowth?
Another name for the water cycle.
What is the hydrologic cycle?
Percentage of our atmosphere that is nitrogen gas.
What is 78%?
Most available oxygen is made by this organism found on the ocean’s surface.
What is phytoplankton?
The process in which animals use oxygen and make more CO2.
What is cellular respiration?
Phosphorus is not found in the free state in nature, it is mostly contained in these 2 sources.
What are rocks and minerals?
The process that turns water vapor into liquid, which causes the formation of a cloud.
What is condensation?
Higher organisms use nitrogen to make these.
What are proteins?
Process responsible for most of the available oxygen in the atmosphere.
What is photosynthesis?
More CO2 is released in the atmosphere today than in the past because of this.
What is the burning of fossil fuels?
Phosphorus is essential to life as it is part the important chemicals that make up your genetic code AKA.
What is DNA?
When water evaporates from a leaf, this process is called.
What is transpiration?
These special bacteria can directly use nitrogen in our atmosphere and “fix” it so other organisms can benefit.
What are nitrogen-fixing?
Some oxygen is made in the atmosphere, when sunlight breaks this down.
What is water?
Coal, oil and natural gas are examples of these.
What are fossil fuels?
In the phosphorus cycle, Phosphorus moves between these two areas of the ecosystem which are eaten by animals.
What is the soil and plants?
When water leaves a body of water after it is heated, the process is called.
What is evaporation?
Animal waste decay by the action of bacteria creates these 2 products rich in nitrogen, and useful for plants to use again.
What are ammonia and nitrate?
The Atmospheric oxygen layer that provides protection from harmful ultraviolet rays.
What is the ozone?
Too much CO2 in the atmosphere may be responsible for this.
What is the Greenhouse effect?
Too many phosphorus-rich fertilizers have this kind of effect on the environment.
What is negative?
When water falls from the sky, the process is known as.
What is precipitation?
Through this process bacteria in the soil can break down the ammonia into the gaseous form of nitrogen, which is not available for use by plants or animals.
What is Denitrifying?
The process which produces CO2 and water.
What is cellular respiration?
