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.
All chordates. a notochord is present at some point in all chordates but sometimes is lost or becomes another structure, like vertebrae
Also idk what “Tregon” so hopefully that didn’t stray from my answer being right
Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifyingselection.
Carlos Linnaeus is considered as the "Father of morden Txonomy."
