Which of the following processes removes carbon dioxide from the atmosphere and converts it to a form of carbon used in the biosphere?
Which biogeochemical cycle does NOT include the atmosphere:
Carbon cycle

Albedo causing ice melt would be an example of this type of feedback loop:
Negative
Positive
Neutral
Stabilizing
Think about melting polar ice and the albedo effect. This situation might add to global warming because _______________.
higher albedo leads to overall higher temperatures.
lower albedo leads to overall lower temperatures.
higher albedo leads to overall lower temperatures.
lower albedo leads to overall higher temperatures.
Using the figure provided, which statement does NOT describe carbon dioxide concentration in the atmosphere?
Darker red colors correspond to higher concentrations of carbon dioxide, which are seen mostly in the northern latitudes.
Near the south pole is a region where the concentration of carbon dioxide is much lower.
Carbon dioxide emissions are greatest in the southern hemisphere.
Carbon dioxide emissions are greatest in the most populated areas.
The graph shows the carbon dioxide (CO₂) concentration of the atmosphere since the year 1000. What was the approximate change in CO₂ level from the year 1000 to the year 2000?
An increase of 135 ppm
A decrease of 135 ppm
An increase of 95 ppm
A decrease of 95 ppm
According to graph 1, the number of sea urchins per test diameter on Shemya Island can be explained by:
Sea otter populations fluctuating, resulting in varying urchin densities
Sea otters only feeding in deeper waters
A presence of sea otters resulting in the urchin population being regulated.
An absence of sea otters resulting in the urchin population only existing in shallow waters
Read the passage. Without the sea otters the kelp forest would quickly deteriorate as a result of sea urchins altering the ecosystem. In this scenario otters are known as being
A capstone species
A keystone species
An invasive species
A prey species
Which of these best describes the relationship shown by this Kelp Forest Ecosystem Pyramid?
The Giant Sea Bass is a predator of the Sheephead
The Giant Sea Bass is the prey of the Sheephead
Sea Urchins are the prey of the kelp
Sheepshead are the predators of the Giant Sea Bass
