When water falls to the earth from the atmosphere.
What is precipitation?
Bacteria convert nitrogen from waste (urine and feces) into ammonia
What is ammonification?
Plants capture CO2 from the atmosphere and use it to make sugar
What is photosynthesis?
One animal kills and eats another for food
What is predation?
This is an example of a negative human impact on the water cycle.
What is deforestation, paving, pollution?
When water returns to the atmosphere via plants
What is transpiration?
When nitrogen gets captured from the atmosphere by bacteria or even lightening.
What is nitrogen fixation?
one organism eats another for carbon
What is consumption?
One organism benefits from the relationship, while the other organism is harmed
What is combustion of fossil fuels?
Water is absorbed underground and can be stored in aquifers.
What is infiltration?
When nitrogen is returned to the atmosphere by bacteria as N2
What is denitrification?
CO2 released into atmosphere as waste from metabolism
What is cellular respiration?
One organism is benefitted while the other is unaffected
What is commensalism?
This is an example of a negative human impact on the nitrogen cycle
What is the use of fertilizers?
Water is not absorbed underground but is collected on the surface of the earth.
What is runoff?
Bacteria in the roots of plants convert nitrogen into a usable form, such as NO2
What is nitrification?
CO2 released into atmosphere from burning
What is combustion?
Both organisms involved benefit
What is mutualism?
the actual area in the ecosystem where an organism lives, including all of its abiotic and biotic resources.
What is a habitat?
The process through which clouds are formed.
What is condensation?
When organisms like bacteria break dead matter down, returning nitrogen to the soil
What is decomposition?
converts carbon from once-living organisms into a fuel source through intense heat and compression, including natural gas, oil, and coal
What is fossilization?
a relationship that exists between two or more organisms that are fighting for the same limited resource
What is competition?
all of the things an organism needs and does within its habitat.
What is a niche?
