;-; Biology Homework Help please...

<p>Hi! "] I know this is not a HELP HOMEWORK BOARD! ;-; But I really need help because I don't understand what's it looking for. I mean I kind of understand but still confused. Could you give me examples what to find?
Here it goes! </p>

<p>Photojournalists can tell vivid stories through photo essays. Ask students to create a pictorial representation [using magazine pictures photos] depicting a chain of events impacting a particular spiecies because of changes in the envirnoment.</p>

<p>Thanks! x.x</p>

<p>The first thing that came to mind for me was what happens to an animal's environment during an oil spill. I am sure that you can find many before and after pictures for many different birds/animals.</p>

<p>hmm...chain of events in relation to a species...so you need to show how the environment change affects the species as a whole...
take for example deforestation affecting...oh I don't know...tigers in Nepal.
1) humans begin to cut down enormous amounts of trees to make room for cities, industries etc (whatever the particular situation may be)
2) tigers are gradually confined to a smaller and smaller space
3) deforesting leads to less plant life(obviously) which leads to less animal life (herbivoral)
4) tigers and other carnivorous species are now facing increased competition for resources
5) There are not enough resources to sustain the same population as before, so the tiger population dwindles to dangerously low numbers.</p>

<p>that's the type of thing that comes to mind
I was originally thinking that you could start with an ecosystem being completely destroyed by say a fire...and then depicting the gradual, natural rebuilding of it...but that doesn't really apply since you're tracking a specific species.</p>

<p>Anyway, I'm not sure how that would be illustrated - but I'm sure it won't be too hard to find things in national geographic and such.</p>

<p>Here's a real life example.</p>

<p>1) Industries in England start emitting black smoke
2) The black smoke covers the trees
3) White moths who previously survived by living on the white trees are now being eaten by predators that can easily spy them on the black trees. The black moths who were previously eaten on the white trees now multiply greatly, since they camoflauge with the background.</p>

<p>Thank you!</p>

<p>lol wrathofgod, can you say TeXtBoOk answer? lol its cool, i love natural selection/descent with modification also. lol</p>
