Biology 1B Final - Ecology portion...

<p>I remember having to read a question several times and still not knowing what the hell it was trying to ask. I’m sure he wanted to be tricky but it ended up just being really confusing. D:</p>

<p>Ah, I don’t think facilitator is a functional feeding group. I put that answer too. Darn it. :[</p>

<p>^ Facilitator was in like 3 of the 4 answers (5th being none of course) lol I think I had Fac, Prods, and Consu? =&lt;/p>

<p>I’m hoping for a B? An A would be nice, but seeing as how I’m not confident about the ecology section at all…and what was the EC answer? I just chose the longest answer. hahah</p>

<p>lol omg what if the answer was none? cuz I think grazers, filterers, collectors and predators are the only ones we learned in the functional group… </p>

<p>oh the EC one… was it… adding the decrease of nitrogen X 100 or whatever… ? lol… eh.
maybe if we went to his office hours, it would’ve helped? I thought he would use the same examples he used in class, but they’re were all pretty different so it took longer to get to the answer…</p>

<p>functional feedings groups: none of the above (as predator has to be part of the answer but it wasn’t present in any of the choices)</p>

<p>EC: A is the answer which is adding lost nitrogen to total amount (the birds eat the plants where the N is fixed)</p>

<p>cohort: follow the deaths and births (females and offspring of females has nothing to do with the question…life tables are always determined solely by birth and death)</p>

<p>what was the answer for the skin pigmentation?</p>

<p>For the extra credit, it couldn’t have been A. I imagine that the birds also eliminated waste from their bodies which has nitrogen in it. That’s why I chose C but, well, who knows.</p>

<p>There were two questions concerning life tables. Both were equally confusing.</p>

<p>The skin questions were definitely bad for me. It seemed like some of the answers contradicted each other. Doesn’t sunlight aid in vitamin D production?</p>

<p>Functional feeding groups - I believe it was none of the above … facilitators have nothing to do with feeding groups unless he was referring to shredders or something. </p>

<p>I chose C for the extra credit as well. Nitrogen in the form of urea enters the environment doesn’t it? Do birds really eat plants? I thought they ate worms/bugs…</p>

<p>Life tables - I don’t remember the first question but the second one was what would you do to construct a reproductive table of a polygamous population and that would be following females only.</p>

<p>What was the Canada/Panama one?</p>

<p>Well, I’m pretty sure that the plant is a short day plant as it didn’t flower in canada where the hour of daylight >12hr. But I also thought it could be a day neutral plant since the temperatures or some other environmental condition could be different. I’m thinking that I’m reading too much into the question and it’s just a short day plant. :&lt;/p>

<p>i chose C for the extra credit question. none of the above for the FFGs. light skin pigmentation aids in production of vitamin D and prevents rickets. wasn’t the plant in the canada/panama question long day? doesn’t panama get more sun than canada? If it flowered in panama and not canada, then it would be a long day (short dark period).</p>

<p>was the lack of female reproducing rats an example of predation on the females?
when the hell did he cover the stuff on skin pigmentation? i missed both those!!!</p>

<p>i said the lack of reproducing rats was most likely because they were immigrant rats. because wasn’t it like, the observer’s backyard? how much predation can go on in a backyard? I dunno. he covered skin pigment in one of the later lectures i think. he definitely went over it at the review session.</p>

<p>at the review he said that he wasn’t going to use any of his examples, and would use new ones to see if we could deduce things from those. so i sort of ignored all that parasite and skin stuff.</p>

<p>now that i think of it. immigrant rats doesn’t make sense. they should still reproduce. blerg.</p>

<p>i also said immigrant rats. i think reasoning was “they come every year”
skin pigmentation was first lecture.
panama has relatively equal sunlight all year since it is in tropics. canada has extremely long days in summer (recall, north pole is pretty much 24-hr sun in summer)</p>

<p>darn it. did the question specifically summer? that seems like something he’s assuming we all know on our own because i don’t remember learning about what locations of the earth get more light during various parts of the year in class.</p>

<p>the question specified that it flowered in summer in Panama and was then transplanted to Canada and then it didn’t flower there.</p>

<p>how the hell am i suppose to know how long sunlight is in Canada? I just picked long day plant because I assumed Panama’s exposure was longer than Canada’s. And thereby choosing E for the next question about preventing flowering…=(</p>

<p>And I put immigrant rats because there was still a lot despite you not seeing reproduction…I mean honestly, the answer should be that I can’t tell if a rat is m/f because if I were observing rats, I wouldn’t give a **** if it were m or f.</p>

<p>i picked long day plant for that canada-panama and i’m pretty sure that’s right…</p>

<p>I agree about the panama thing. When I first saw it, I was like, this is unfair, what if I don’t know that there are longer days in canada. </p>

<p>i also put immigrant rats for that question. this was because it said that i never saw any rats reproduce there. so they had to have come from somewhere. i was leaning towards E where it said that i couldn’t tell the difference between males and females but i assumed that was a joke answer.</p>

<p>**** i’m going to *<strong><em>ed if i don’t end up getting at least an A- in this class… my GSI screwed us over by making lab really easy so now everyone is getting dropped a *</em></strong>load of points.</p>

<p>when do grades come out?</p>

<p>soon soon.</p>

<p>really 8888? how do you know? do they get posted online or something? specific dates?</p>

<p>(excuse the annoying grade-whoring, but that final just really ****ed me off and i REALLY wanna know how i ended up doing)</p>
