What conditions are necessary for an ecosystem to be self sustaining?
The ecosystem should have, in general, effective negative feedback relations between it's elements. For instance, a simplest ecosystem "predator-prey-limit" possess 1 negative feedback relation: 1. The more predators are, the less prey is. The less predators are, the more prey is. The other relation in this system is positive feedback: 2. The more prey is, the more predators are. The less prey is, the less predators are. If there would be no negative feedback relation (1), then population of both predators and prey would reach ecosystem limit (alimentary and/or area) and then extinct. rowlat@gmail.com

What is the difference between a population community and an ecosystem?
A population is a single species within a specific geographical area. Geographical area can be literal (like a tide pool) or artificial (a 25'x25' plot of forest) depending on the study. A community is made up of all the individual animal species living within a specific geographical area. For example, in a tide pool the community would be the seastars, crabs, barnacles, algae, etc. An ecosystem is all the individual species living within a specific geographical area plus all abiotic(non-living) factors with which they interact. Using the tide pool example, an ecosystem includes all the animals above but also the seawater, rocks, minerals, wind, sunlight, etc.
