Definitions
This refers to the movement of elements through ecosystems on a global scale.
What is Biogeochemical Cycling?
The molecules of all living things, aka organic material, are based on this element.
What is Carbon?
This is the most abundant element of all atmospheric gases.
What is Nitrogen (in the form of N2)?
During lightning fixation of nitrogen, this substance is responsible for transporting nitrogen oxides (NOx) in the air to the soil after N2 is split.
What is Water?
This refers to all the living and non-living things in a specific region that interact with each other.
What is Ecosystem?
This refers to any material that stores excess carbon.
What is Carbon Sink?
These are the elements that are essential for living organisms in large amounts.
What is Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus, Sulfur?
This is the primary way that stored phosphorus is released.
What is weathering/erosion?
This is the primary storage location of Phosphorus before it is introduced into food chains.
What is rocks?
This refers to all the different types of living organisms that inhabit an ecosystem and interact.
What is Community?
This refers to a type of single-celled organisms in the root of legumes that can convert Nitrogen into ingestible forms for food chains.
What is Nitrogen Fixing Bacteria?
This is one element that is still essential for the body, only in trace (small) amounts.
What is either of:
- Calcium, Magnesium, Potassium, Zinc, Sodium, Iron, Copper, Manganese, Selenium, Iodine, Cobalt
This is one example of a Carbon sink.
What is either of:
- Forrest
- Ocean
- Human beings
- Fossil fuels
Nitrogen fixing bacteria are often found in the roots of this plant type.
What is legumes? (Beans, peas, lentils, etc.)
This refers to all the individual organisms of a given species in an ecosystem. Aka the total count.
What is Population?
When photosynthetic organisms (producers) take up carbon dioxide and convert it into a more organic-friendly molecule.
What is Carbon Fixation?
This is one way that organisms use the elements that are essential for them.
What is either of:
- Metabolism
- Building blocks
- Cell functions/repair
- Etc.
In food chains, this is one way humans are responsible for re-introducing nutrients, like phosphorus and nitrogen, back into their ecosystem.
What is either of:
- Decomposition
- Urination/Defecation
This is where enormous amounts of carbon are located in the form of calcium carbonate (CaCO3).
What is skeletons/shells of marine organisms?
This is the main sugar that is produced by the producers and passed along food chains. It serves as the primary form of energy breakdown for humans.
What is Glucose?
What is Lightning Fixation?
This is the most abundant element in the human body.
What is Oxygen?
Overuse of phosphorus in this product can lead to in surface runoff of excessive phosphorus resulting in algal blooms that can kill aquatic organisms.
What is Fertilizer?
Of the three cycles discussed in this unit, these are the ones that are essential for our DNA.
What is Nitrogen, Phosphorus, Carbon?
This how much energy is lost across each trophic level.
What is 90%?
