Scientific Method
Make an observation
What is the first step in the scientific method?
A graph showing the increasing amounts of CO2 in the atmosphere over time since 1958.
What is the Keeling Curve?
The form of carbon found in the atmosphere that aids in the greenhouse effect.
What is carbon dioxide, or CO2?
The inert form of nitrogen in the atmosphere.
What is N2 gas?
This type of feedback balances a loop.
What is a negative feedback?
Producing the same result consistently.
What is reproducibility?
Organisms that are brought into a new area and displace local populations.
What are invasive species?
Plants process carbon through this method.
What is photosynthesis?
The process of turning nitrogen from N2 gas into available nitrogen for plants.
What is nitrogen fixation?
A biological community and its physical environment.
What is an ecosystem?
The second step in the scientific process.
What is create a hypothesis?
This form of energy exists in objects that are moving or currently at work.
What is kinetic energy?
What is respiration?
Organisms that are the main conversion of nitrogen in the Nitrogen Cycle.
What are bacteria?
As energy flows through trophic levels it forms this shape.
What is a pyramid?
A hypothesis that has been tested repeatedly and not proven false.
What is a scientific theory?
This can occur in a system that has experienced a great disturbance.
What is a state-shift?
Stored carbon in plants.
What is biomass?
This process can form either the ammonium or ammonia ion.
What is ammonification?
Organisms at the start of a trophic level.
What are producers?
Cannot be proven false, cannot be tested, lacks objective obervations.
What is pseudoscience?
A large "island" of plastic that was discovered floating in the Pacific Ocean by Charles Moore in 1998.
What is the Great Pacific Gyre?
Car and factory fumes and forest fires.
What are anthropogenic sources of carbon?
Extreme leaching of nitrates cause this to happen in lakes and oceans.
What is eutrophication?
Organisms that feed off other organisms?
What are consumers?
