My professor is offering no help and the book is not helping me much either. The question he is asking is :

The population density of large carnivores is always less than their prey. Using the idea of an engery pyramid and the 10 % rule of energy transfer, why does this occur?

If you could, elaborate or help... Anyhing that can help me further to the correct answer he is looking for.. Thanks in advance!!

- Identify the geographical location of each mountain belt?

-What rock types are present in each mountain formation? Is one type of rock more prevalent than others?

-What other geological features are present in the area that may have contributed to the mountain formation? Consider continental edges, streams, volcanic activity, earthquake faults, extreme surface temperatures, and other factors.

-and What visual features indicate whether this mountain
range is in an early stage of development or in a later stage?

I live in southern California I wish Dean come to California. I check Dean's project path look still keep go westward and I think Dean will may impact south Texas or Mexico and still keep to go westward over Mexico next week although Dean will dissipate over mountains in Mexico but still tropical moisture of remnants Dean bring some need rain to California if system keep go westward. I wish this! I don't want Dean turn northward to U.S. gulf coast or Texas that don't need rain because have many summer storms. I say keep Dean go westward toward California. Do you agree with me?

I wish heavy rainfall of remnants Dean in California but I know Hurricane or tropical storm Dean will die over mountains or land in Mexico. Maybe be very interesting in Tropical system from Atlantic has rare to go toward U.S. southwest even California. I hope this!
