Question 1

Photosynthesis

Answer 1

Process in which producers make their own energy. This takes in CO2 from the atmosphere and starts the carbon cycle.

Question 2

Cellular Respiration

Answer 2

Process in which organisms create ATP. This returns Carbon to the atmosphere in the carbon cycle.

Question 3

Nitrogen Fixation

Answer 3

Process in which soil microbes make atmospheric nitrogen useable for most organisms. This is part of the nitrogen cycle.

Question 4

Denitrification

Answer 4

Process in which nitrogen is returned to its atmospheric state. This is how nitrogen returns to the atmosphere in the nitrogen cycle.

Question 5

Carbon Cycle Processes

Answer 5

Atmosphere –(photosynthesis)–> Producer
Producer–(consumption–> Herbivore-
Herbivore–(consumption)–> Carnivore
All of them can die and be decomposed.
Soil–(cellular respiration)–> atmosphere
Cellular Respiration can also occur at any time for any organism.

Question 6

Nitrogen Cycle Processes

Answer 6

Atmosphere–(nitrification)–> Soil
Soil–(taken through roots)–> Plants
Plants–(consumption)–> Herbivores
Herbivores–(consumption)–> Carnivores
After death and decomposition, it is returned to the soil.
Soil–(denitrification)–> Atmosphere

Question 7

Compare and Contrast the Carbon Cycle and the Nitrogen Cycle.

Answer 7

They follow the same path for the most part, however, how the matter goes to and from the atmosphere is different. Carbon leaves through photosynthesis and enters through cellular respiration. Meanwhile, nitrogen exits through soil microbes’ nitrification process and enters through their denitrification process.
