At the moment bees are dying out, if they did. There would be no bees to pollinate plants flowers to grow crops for consumption etc.

It can happen in several ways...One common way that a "crash" of an ecosystem is taught refers to a "keystone species". Example: In an area of the Pacific ocean, the sea otter is considered a keystone species, and when removed (or drastically reduced) the ecosystem collapses.  The otters feed on sea urchins which feed on kelp roots. When the otter is removed, the urchin population grows unchecked, and continues to feed on the kelp much more extensively, drastically reducing the kelp forests, and causing negative impacts to many fish and other aquatic species.

an ecosystem can self destruct if one cycle is broken. like for example, the cycle of life if one doesn't reproduce, it would only stop there and nothing more would happen, after some time, the population, i think, will be wiped out.
