In the carbon cycle, animals can release carbon back into the cycle through ___________ or through ____________.
respiriation.....decomposition
burning....photosynthesis
respiration....photosynthesis
decomposition....photosynthesis
Which of the following is an example of human impact on the carbon cycle?
The increased production of methane gases from cattle farms
The burning of fossil fuels
The cutting down of trees for lumber
None of the three
All off the three
The burning of fossil fuels releases which of the following gases into the atmosphere?
oxygen
nitrogen
carbon dioxide
water vapor
What impact can deforestation have on the carbon cycle? Select all that apply.
Carbon dioxide is released into the air as trees are burned
The amount of nitrogen-fixing bacteria increases
Photosynthesis decreased, thereby increasing the amount of carbon dioxide in the air.
Photosynthesis increases, thereby increasing the amount of carbon dioxide in the air.
Which of the following is the greatest concern regarding the use of fossil fuels?
polluted waters
increased runoff
climate change
eutrophication
Where is the largest carbon sink (storage) of carbon on earth located?
in the atmosphere
in permafrost
in the ocean
in freshwater
This is a way of describing all the carbon an individual, organization, or country puts into the atmosphere.
carbon source
carbon footprint
the Greenhouse Effect
photosynthesis

fungi
plants
How do human obtain the nitrogen they need for nucleic acids, amino acids, and enzymes?
From bacteria
From the atmosphere
From the food they eat

Question 17

What part of the water cycle does this represent?

The gases that make up Earth's atmosphere have changed over time. Scientists measure the levels of carbon dioxide (CO2) in Earth's atmosphere. The simplified Carbon Cycle Model shows locations where carbon is stored and processes that move carbon from one location to another.


Scientists can use carbon cycle models to help make predictions about the amounts of carbon in different locations. Use this Carbon Cycle Model to identify all the processes that would decrease CO2 in the atmosphere if the rates of these processes were to increase.
photosynthesis
fossil fuel combustion
diffusion into the ocean
cellular respiration
diffusion into the atmosphere
Urban areas have a high percentage of impermeable surfaces such as roofs and roads. Which of the following changes would you expect to occur in the water cycle?
Increased runoff
Decreased evaporation
Increased infiltration
Decreased condensation
