Compare primary succession and climax community. In your discussion, identify how long-term survival of species is dependent on resources that may be limited.

I don't come here until it's a last resort. You should probably see what the case is before you insult someone. This is the only question so far that I've had a problem with, and I've been trying to figure it out for about three days now.

Primary sucession: A type of ecological sucession that occurs in a virtually lifeless area, where there were originally no organisms and where soil has not yet formed.
So basically life came to a place that had no life to begin with.
Now the opposite of that is the climax community. A place where there is so much life that competition will eventually lead to mass migration or mass extinction and the place becomes empty
Second question
Limited non renewable resources will make a species more and more competitive as time goes on. Thus each will kill the other either knowingly or by taking the resources to itself.

Screw your detractors. At least you use both proper spelling and grammar.
It's been a long time since I took biology, but primary succession occurs in situations like recovery after a forest fire or recession of a body of water from land. The first plants in are non-specialists, "weedy"; they have a lot of access to light, but soils and nutrients may be poor. They create an environment where other plants can grow, etc. Things change relatively rapidly. Most plants are young.
The climax community is relatively stable. Most plants are represented over their full life-cycle. The set of species changes relatively slowly.
Maybe when you're done you can expand some of the stubs on Wikipedia.

Dear S.-P.
Ignore the insensitive brutes. Engineer-... is correct. Let me add that a species that can survive in an environment that has a succession of disappearing (exhausted) or limited resources would have to be not particularly specialised and would have developed many different biochemical pathways to handle many different and perhaps novel energy sources. Rats are a good example of this. So are cockroaches. (they have not changed much in at least 250 million years, and can survive on soap, shoe polish etc. etc.) An extreme primary ecological niche is a very isolated emergent island. Lichens blow in settle in sheltered spots and leach ions out of rock and break down rocks with organic acids. The algal partner in this symbiosis provides energy through photosynthesis, and the fungus provides shelter and exotic chemicals. Eventually their breakdown products forms a little soil for seeds to germinate and grow in. etc.
Hope that supplements Eng.'s answer.
Dan.

think about the meaning of a climax, now apply that to a community or species like humans, see how they may use resources, do the same for the other part

Please see this link for an outline of a study guide relating to your question. I think the definitions given just might help. Hope so!

I should give you a wrong answer so that you get the question wrong. You deserve to fail for cheating.
