Oh, right! Well, I assumed we just had to find the carrying capacity of the first population, because it said that it didn't interact directly or indirectly with the second population. So we just read the graph, then multiplied it by 2 because the graph only counted one of the sexes (I think it was males). I can't remember what number that resulted in, but it was one of the choices so we went with that.

Wow! I didn't see that it was only one of the sexes. So it was 1800?

Yeah, if that was the 4th option. At least, that's what we went with. I don't know if it was what they were looking for or not.

We got 2nd and we were the first ones out. It took us about 8 minutes. He didn't start til about 5 minutes after he was supposed to and we left at like 12:13. I don't know if someone could finish much quicker than that so I'm thinking we missed one unless some people were speedy thinkers that day lol.

Is there not going to be Ecology next year? I looked at the schedule for the workshops for coaches this year...and it isn't on there. I'd be really sad if theres not

I'm pretty sure it's switching to water quality.

Don't be too sad - its basically the ecology of estuaries, with a little ID and salinometer-building thrown in.

Its not that difficult - we built a crude one in chemistry last year. The only downside is that everyone will be basically building the same exact one..
