7. We know that energy and water are vital to the survival of an ecosystem. Based on this knowledge, why does conservation of resources become a necessity?

9. Discuss the relationship between organisms, energy resources (including availability) and the impact that this has on an organism in an ecosystem. You may find it helpful to choose a specific organism and ecosystem to use as an example to answer this question.

im stuck on these two problems. any help is appreciated.

Find the first derivative of f(x). Enter exp(10 x) when you write the exponent.

f'(x)=

For the function f(x) there are two critical numbers, which correspond to a local maximum and a local minimum.
The x-coordinate of the LMAX is
The x-coordinate of the LMIN is

Ok, picture this:

A sailboat is on flat, calm water, with no wind. The sails are open. A fan is on the rear end of the sailboat blowing an unlimited amount of air into the sails.

Would the sailboat go forward, or reverse?

For this function there are four important intervals: (-\infty, A], [A,B],[B,C], and [C,\infty) where A, B, and C are the critical numbers.

Find A, B, and C
At each critical number A, B, and C does f(x) have a relative min, a relative max, or neither?
A=
B=
C=

I read in this one book, devil's teeth, that two sea lions were released in the shark-infested Farallon Islands. The first one, eDog, swam safely to shore. The second, Swissy, was released, photographed for about thirty seconds, and then promptly bitten in half by a 17-foot, 2 ton great white shark named gouge (for the large boat prop marks on his head).

The book says that the shutter of a camera went off exactly as the great white breached out and hit Swissy, and I assumed that it would be one of those "everywhere" pictures that you see. It must have been too violent or was lost or something, because I can't find it anywhere on google, ask, dogpile, etc.

All I can find is some brief mentionings of the pinniped in certain sea lion rescue-and-release articles. It bluntly puts the whole "ripped-in-half-by-a-giant-shark" thing and moves on to radio tags and whatnot.

The point is, I can't find anything more on them than that. So PLEASE help me, I want to learn more.
