Cycles

The processes of photosynthesis and respiration are tied together in
1. the carbon cycle and oxygen cycle
2. the nitrogen cycle and water cycle
3. the nitrogen cycle
4. the phosphorus cycle
Nitrospira and nitrosomonas are
1. fungi
2. bacteria
3. small fish
4. plants
In addition to helping to remove nitrogenous wastes, the plants in the aquarium provide the fish with
1. carbon dioxide
2. oxygen
3. bacteria
4. water
When the fish is provided with so much food that it cannot eat all of it, the excess food
1. helps to remove nitrogenous wastes from the aquarium
2. adds to the nitrogenous wastes in the aquarium
3. can be absorbed by the plant for photosynthesis
4. kills bacteria
The water cycle process labeled #1 is
1. condensation
2. precipitation
3. transpiration
4. evaporation
The water cycle process labeled #2 is
1. condensation
2. evaporation
3. precipitation
4. transpiration
The water cycle process labeled #3 is
1. condensation
2. evaporation
3. precipitation
4. transpiration
The water cycle process labeled #4 is
1. condensation
2. evaporation
3. precipitation
4. transpiration
As the air temperature increases, the rate of process #3 _______________ and the rate of process #1 ______________.
1. decreases / decreases
2. decreases / increases
3. increases / increases
4. increases / decreases
Process #1 removes carbon dioxide from the atmosphere by means of
1. respiration
2. photosynthesis
3. decomposition
4. deamination
5. evapotranspiration
Processes #2 and #5 add carbon dioxide to the atmosphere by means of
1. respiration
2. photosynthesis
3. decomposition
4. deamination
5. evapotranspiration
In addition to carbon dioxide, what chemical compound is released into the atmosphere as a result of processes #2 and #5
1. oxygen, O₂
2. water, H₂O
3. ammonia, NH₃
4. phosphate, PO₄^3-
The burning of fossil fuels
1. requires O₂ and releases CO₂
2. releases O₂ and CO₂
3. requires O₂ and CO₂
4. releases O₂ and requires CO₂
The source of the carbon in fossil fuels is
1. dead plant and animal matter
2. limestone deposits
3. ammonia from proteins
4. ocean water
Substances #1 and #2 are
1. carbon dioxide
2. water
3. glucose
4. oxygen
Substances #3 and #4 are
1. carbon dioxide
2. water
3. glucose
4. oxygen
