What types of nutrient cycles do you need to know for this event?

In addition to that question (which nobody seems to know the answer for anyways), what types of information do you definitely need to know for the biomes? Region, climate, adaptions, and what else?

There really aren't good answers to either question. There is no specific rule that says which cycles you need to know. I can remember being tested on the water, nitrogen, and potassium cycle. But you can certainly be tested on the others. Everything you listed about biomes is fair game. I try to learn as much as I can about the biomes. Often times some very trivia-like questions will show up about them. The general ecology is the easy part to learn, the biomes are really the hard part in my opinion.

Now that you get a sheet, the cycles should be pretty easy. I'd put down all the major cycles, including potassium, sulfur, nitrogen, water, and phosphorous.

can someone explain to me survivorship curves?
EDIT:
also, I googled and wikied the word "crovasculating" because I didn't know what it meant.
It's on the Virginia sample test, around problem number 25.. sry

I think that is a graph of two animals one being a preditor and the other being it's prey.

For example, there is a rabbit and a fox, and their population size is represented by two differrent lines on one graph. As the rabbit population goes up the fox population goes up as well. So both lines increase. Then because the rabbit population is being consumed rapidly it drops, and by domino effect there are too many fox and too less rabbits so their population drops as well, and so on.

Also, I think this has been discussed before, maybe in last years thread or some thing.

Here's an example graph

Here are some websites:

Survivorship curves model the lifespan of populations against time. There are 3 types, type 1 is populations whose death rate stays low, then rapidly increases as they get older. Examples would be humans and elephants. Type 2, which may be the oddest, has a constant death rate throughout their lifespan, the only example I really know is squirrels. Type 3 is organisms who have a very high death rate right before birth and once they survive that the death rate slowly decreases. That is probably the most common, and a lot of fish and other organisms that lay a lot of eggs are type 3.

Question 25. I couldn't find it on google either, and the only other place I have seen it is the Mentor test, Q. 21. It is the same question, as are the questions above and below. Some test bank writer probably threw it in there because they couldn't think of a more plausible wrong answer. I don't think you need to worry about it.

sorry this is kind of random but am i the only person that thinks that a resource sheet is really stupid for this event?

Nope. Read the beginning of this thread.
