Answer:
- Interspecific competition between sea urchins and Stellar's sea cows
- Predation fo sea urchins by sea otters
Explanation:
As urchins and Stellar's sea cows feed on seaweed, since these algae are low in quantity, these two organisms end up competing for food, creating an inter-specific competition, which occurs when two organisms compete for the same resource within a same ecological niche. However, as the hedgehog has advantages in this niche, this competition was interrupted.
The otters' predatorism in relation to sea urchins was also interrupted, as the otters reached a very low population level, failing to control the hedgehog population and generating an environmental imbalance.
