Biology 1B Final - Ecology portion...

<p>does anyone have any tips for studying for this portion of the exam?</p>

<p>resh said he would put a lot of conceptual questions and his sample questions online confused the heck out of me.</p>

<p>any tips?</p>

<p>Some of the questions are just worded in a tricky way is the way I see it…like how does P enter the atmosphere? It doesnt. doh.</p>

<p>and i don’t understand the lizard question…wouldn’t decrease emigration give you more adults as well as increased immigra? so why is the answer choice only increased immigra?</p>

<p>what the hell is standing crop? I’ve webcasted all his lectures and written down almost word for word everything he’s said, but i can’t find standing crop anywhere…=(</p>

<p>Definitely tricky questions.</p>

<p>Decreased emigration wouldn’t give you more individuals. Emigration is when individuals leave. So there wouldn’t be an increase in individuals but a smaller decrease. Increased immigration means more individuals are coming in and that is when you see an increase in pop.</p>

<p>For standing crop, the only justification that I saw for that question was that it was basically process of elimination. We are supposed to know all the other words so, by process of elimination, standing crop was the answer.</p>

<p>thanks aerials, that explanation makes sense cuz i was confused about that emigration question too. wow, very tricky lol.</p>

<p>as for standing crop, he definitely did not cover that. these questions might be really old.</p>

<p>good looking out. haha i just keep thinking numbers and that the young would grow old presumably… haha</p>

<p>two more questions:

  1. What does it mean by fail to colonize a new area?
  2. Matter is just used, energy is released yes? (they can’t be converted and whatnot)</p>

<p>I’ll try taking a stab at the questions.</p>

<p>1) The invasive species have not evolved in the habitat they have been introduced to so they may not be competitive in the new community due to competition or resource limitation. Therefore, they may fail to colonize a new area. An example would be the oysters that were brought over from the east coast but could not adapt to the new environment.</p>

<p>2) Matter (as in the C, P, N, H2O) can be cycled through the system, but energy cannot because it it only goes up the trophic ladder.</p>

<p>I honestly think some of these questions are poorly worded. My guess is that we will have to read the questions carefully because Dr. Resh will most likely put in some trick questions, based on the sample questions.</p>

<p>Nice answers, zjodak. Being on CC gets answers quicker than going to his review session.
Can anyone explain life tables?</p>

<p>Yeah, he’ll probably put some really tricky scenarios and we’d have to infer a lot from that. I’ve been playing with the thought that maybe he wants to make his part really hard because we all did so well on Huelsenback’s midterm. haha.</p>

<p>don’t remember life tables too well…but I thought all you had to know about them was that they form the survivorship curves…hmm</p>

<p>thanks zjo for the answers! Are all the questions gonna be multiple choice? I remember reading that ecology questions were just hard to make in the first place (though I don’t know why…my AP Bio teacher made plenty that were both easy and hard and her tests were I’d say nearly on par with Feldman’s and definitely harder than Huelsenbeck’s =) </p>

<p>Lastly, you think he’ll test on the different experiments? Lol. I hate it when he asks what kind of experiment is this? Like what kind was it with the sheep and the boots? Supplemental?</p>

<p>cattle and boots is exclusion right?</p>

<p>yeah, exclusion of the larvae from contacting the cattle skin</p>

<p>Did anyone else feel like Resh’s section was awkwardly worded and basically pretty ****ty? :[
There goes any chance I had of a good grade.</p>

<p>that isht was haaaarrrd</p>

<p>yeah. i hope there’s a curve!</p>

<p>exactly what I came on here to say aerials. he’s trying too hard and then the questions just come out weird and the tricky answers don’t help either at 8 in the morning (predation one INcreases while the other INcreases. nasty.) I thought Huelsenbeck’s portion would get extremely hard because I never paid attention in the last two lectures so I didn’t even know what that fauna was…=( Cambrian anyone?</p>

<p>Wikipedia says it’s pre-cambrian…</p>

<p>Some of Resh’s questions were just weird - e.g., functional feeding groups in rivers, greatest difference between NPP/GPP…</p>

<p>what the hell is the difference between “offspring of the cohort” and “offspring of the females of the cohort”?</p>

<p>lol greatest difference i just put no difference after reading that question about 10 times I still couldn’t come up with a reason…boooo</p>

<p>so according to the first sheet… we will be getting the scantrons/scores back from GSIs?</p>

<p>at least i can now move on because i no longer have any hope for a good grade.</p>

<p>If you have no hope for a good grade, then why didn’t you skip the final? This way, you’ll get an F in the class and get a chance to retake it.</p>

<p>It’s better than having a C- or whatever without a make-up grade on your transcript.</p>

<p>uhm yeah, ecology was a mix of easy and really tough/weird questions… It seemed like some were intentionally tricky and didn’t really have 1 clear answer… so annoying, i hope they curve!
I put number of females, because usually by knowing the number of females - you can get a better indication of offspring. and are facilitators part of the functional feeding group?</p>
