Step-by-step explanation:

When the comb jelly, Mnemiopsis leidyi, was accidentally introduced into the Black Sea, it had a significant impact on the ecosystem. Comb jellies are voracious predators that feed on plankton, which disrupted the food chain and led to a decline in native species. The introduction of Mnemiopsis leidyi caused a collapse of the Black Sea's fisheries, as important fish species drastically decreased in numbers.
