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.
An organism that exhibits a head with sensory equipment and a brain probably also have receptors, which capture the stimuli of the environment and transform them into a nervous impulse, and organs of the senses that are the communication channels we have with the environment and thanks to them we understand and interpret the environment, they are: vision, hearing, smell, taste, and touch.
