The emerald ash borer is an invasive insect in the United States. Invasive species are not native to the place they invade. As a
result, they often have no predators in their new ecosystem
Emerald ash borers burrow into and kill ash trees. They have no natural predators in the United States
How does the presence of emerald ash borers affect the flow of energy through ecosystems in the parts of the United States
where they live?
A.
They decrease the amount of energy available to ash trees
OB. They decrease the amount of energy available to animals who eat the seeds of ash trees
c. They increase the amount of energy available to secondary consumers.
D. They increase the amount of energy available to primary consumers.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
