100
Another name for the water cycle.
What is the hydrologic cycle?
100
The atmosphere is mostly made of this state of matter.
What are gases?
100
This type of life form stores the sun’s energy in their bodies as plant matter.
What are Producers?
100
Cyanobacteria changed Earth’s early atmosphere with this process.
What is they converted CO2 into O2?
100
These nutrients are needed in large quantities.
What are Macronutrients?
200
This process is carried out by bacteria that convert N2 into a nitrogen compound that can be used by plants and animals.
What is nitrogen fixation?
200
The hydrosphere is mostly made of this state of matter.
What is liquid (Water)?
200
This type of life form can not get energy from the sun and eats other life forms to gather energy.
What are Consumers?
200
The free oxygen supply is mostly replenished by what form of life?
What are Plants?
200
These are essential nutrients in the production of protein (muscles).
What are nitrogen and sulfur?
300
Carbon takes this form in plants.
What are carbohydrates such as starch or sugar?
300
The geosphere is mostly made of this state of matter.
What is solid (Rock and Dirt)?
300
Directly or indirectly, nearly all life depends on this source of energy.
What is the sun?
300
Plants and animals maintaining a constant level of CO2 and O2 in the atmosphere is an example of this concept.
What is dynamic balance?
300
These are some of the macronutrients.
What are Carbon, Oxygen, Hydrogen, Nitrogen, Phosphorus, Sulfur, Calcium, and Potassium?
400
These life forms use free oxygen and gives off CO2 as a waste product.
What are Plants, Green Algae, and Cyanobacteria?
400
Matter that is alive is in this “sphere”.
What is the Biosphere?
400
The energy that consumers get from eating plants is stored in this form.
What are Carbohydrates such as sugar and starch?
400
These loops are critical in regulating our environment.
What are feedback loops?
400
How much free oxygen (O2) was in Earth’s early atmosphere?
What is almost none?
500
Because most of it is trapped in the geosphere.
Why is phosphorus said to move in a sedimentary cycle?
500
This sphere is interaction of the biosphere and all of the other spheres.
What is the Ecosphere?
500
This biological process converts stored chemical energy into heat, kinetic energy, and the creation of proteins.
What is Cellular Respiration?
500
The cycling time of matter in each sphere is different and depends on this.
What is the Form of the Primary Reservoir?
500
This macronutrient moves in a sedimentary cycle and is important in regulating our metabolism.
What is Phosphorus?
