the introduced species compete for resources more effectively than native species.
b)
their removal from their native habitat has a negative impact.
c)
introduced species often become endangered when they are placed in a new habitat.

9.
How does the burning of fossil fuels contribute to the net increase in atmospheric carbon?
a)
Carbon released by burning is not in a form that can be readily absorbed by plants, leaving residual carbon in the atmosphere.
b)
Photosynthesis is reduced by virtue of increased smoke and haze.
c)
Carbon that has been sequestered underground is added to the carbon cycling between the atmosphere and the biosphere.
d)
Carbon released by the burning increases plant growth, producing more carbon for the atmosphere.

12.
A field is abandoned, and an invasive plant that can live in nutrient-poor soil moves into the field. If the land is later cleared of this invasive species and it is discovered that the soil has an abundance of nitrogen compounds, what conclusion can best be made?

More rock was weathered and broken down to release nitrogen compounds.
b)
The plants were able to produce nitrogen in their leaves.
c)
The plants used up all of the phosphorous and potassium and left the nitrogen behind.
d)
Bacteria in soil and in root nodules converted free nitrogen into nitrogen compounds.
