Your right it is mutation
The correct answer is - species.
The extinct Caribbean monk seal was a species of seal that lived in a relatively small area in only one prat of the planet. Also, this species lived in waters that are not typical for the other seals. Because the Caribbean monk seal was isolated from the other species of seals, its genes over time became different enough from the other types of seals so that they can not mate and produce offspring between each other. While the isolation made it a unique type of seal, it was also very unfortunate because it meant that it can not be saved, at least in a mixed form, by mating with other seals, so this species of seal went extinct.
Answer:
When the walleye pollock population decreased, there were more zooplankton available for the moon jellies to eat. Since the jellies had more energy storage molecules, they were able to reproduce more. This lead to more births than deaths in the moon jelly population, which caused the jelly population to increase.

Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
