Characteristics of a Living Thing
Levels of Ecological Organization
Water Cycle
Carbon Cycle
Nitrogen Cycle
100

Criteria for life that says organisms need to contain this to be considered living.

What is Made of Cells?

100

Classified as an individual member of a species or population

What is an organism?

100

This step forms clouds due to water forming on dust particles

What is condensation?

100

Step in the carbon cycle that has plants taking in CO2 and making Glucose

What is Photosyntheis?
100

This step takes atmospheric nitrogen and covers it into ammonia

What is Nitrogen Fixation?

200

In order to be considered living organisms, you must be able to respond to these external or internal factors.

What are stimuli?

200

Multiple individuals of the same species living together

What is a population?

200

This step has water collecting in areas above ground leading to the formation of puddles, ponds, lakes, etc.

What is Runoff?

200

The process in the carbon cycle that we as mammals do taking Glucose and making it into CO2

What is Cellular Respiration?

200

Bacteria take decaying matter and converts it into Nitrogen

What is decomposition

300

This is the genetic material that a living organism must contain in order to be considered living. (Hint: These are types of nucleic acids)

What is DNA and/or RNA?

300

This is our planet and all the biotic and abiotic factors on it

What is the Biosphere?

300

This step is where atmospheric pressure causes clouds to start dropping water from the sky

What is Precipitation?

300

This is the process of burning things to produce CO2

What is Combustion?

300
Bacteria converts nitrogen from waste into ammonia

What is Ammonification

400

These are the two functions that an organism must be capable of in order to be considered living.

What are Growth and Reproduction?

400

Multiple populations of different species living together

What is a community?

400

This is the step where water molecules reach the temperature in order for it to turn into a gas and go into the atmosphere

What is Evaporation?

400

This process turns carbon from decomposed nutrients to Fossil Fuels

What is Fossilization?

400

Bacteria takes ammonia and converts it into usable nitrogen

What is Nitrification

500

Living organisms must be able to adapt to this specific thing

What is the environment?

500

this level recognizes multiple ecosystems that share similar characteristics, such as the amount of annual sunlight and precipitation, but are located in different parts of the planet

What is a Biome?

500

This step is the only one that directly involves living organisms, using it for nutrients and then causing it to evaporate into the atmosphere

What is Transpiration?

500

Taking wastes and dead matter and turning them into carbon molecules for the soil

What is decomposition?
500
Without this, the nitrogen cycle would not be able to function

What is Bacteria?

600

Living organisms must be able to do this process, which consists of both consuming energy and producing waste.

What is metabolism?

600

The same size as the community level, but includes abiotic factors surrounding the community

What is the Ecosystem?

600
Water that collects below ground as groundwater within wells and underground aquifers is called 

What is Infilltration?

600
This step is where things eat other things for Carbon

What is consumption?

600
Bacteria takes nitrogen and converts it back into a gas

What is Denitrification?
