Well I think that the factor of extiction of one species ot he introduction of an alien species into the ecosystem will affect the food chain, for some species will mean going up and for other species will mean going down in the food chain. That is why many countries forbid the introduction of foreign plants or animals into their ecosystems. One big example I can think of is the migration of African bees in America; beginning in the south they have traveled upwards causing havoc in the ecosystems and the only effective barrier they've found is the temperature, being a tropical species they get eventually blocked by northern temperatures, hope they don't breed a new bee which can support lower temperatres. Hope that help.
