Question 1

Nitrogen Reservoir

Answer 1

Stores Nitrogen - Atmosphere is largest

Question 2

Nitrogen Fixation

Answer 2

Movement of carbon through atmosphere, organisms, oceans, and Earth’s crust

Question 3

Autotrophs

Answer 3

Organisms that can make their own food - plants

Question 4

Heterotrophs

Answer 4

Cannot make their own food - animals, herbivores, omnivores, carnivores

Question 5

Stages of the nitrogen cycle

Answer 5

Nitrogen fixation
Nitrogen assimilation
Ammonification
Nitrification
Dentrication

Question 6

Main carbon reservoirs on Earth

Answer 6

Oceans, Fossil Fuels, Atmosphere, Biosphere

Question 7

Aerobic Respiration

Answer 7

oxygen used to make energy from carbs

Question 8

Anaerobic Respiration

Answer 8

occurs without oxygen - releases less energy but quicker than Aerobic

Question 9

Specific Heat Capacity

Answer 9

q=mCAT

Question 10

human activities impact the carbon cycle

Answer 10

burning fossil fuels
deforestation

Question 11

Compare Photosynthesis and aerobic and anaerobic respiration

Answer 11

Photosynthesis is the process by which plants convert sunlight into energy, while cellular respiration is the process by which cells release energy from glucose

Photosynthesis is endothermic (requires energy input), while cellular respiration is exothermic (releases energy

Photosynthesis produces glucose and oxygen, while cellular respiration produces carbon dioxide and water

Question 12

Aerobic Respiration

Answer 12

oxygen is used to make energy from carbohydrates

Aerobic respiration occurs with oxygen and releases more energy but more slowly

Question 13

Flux Mechanism

Answer 13

crystal growth method

where starting materials are dissolved in a solvent (flux), and are precipitated out to form crystals of a desired compound

Question 14

Chemosynthesis

Answer 14

food is made by bacteria or other living things using chemicals as the energy source, typically in the absence of sunlight
