The decline of the smaller sea otter population significantly disrupted Pacific Coast ecosystems by allowing sea urchin populations to explode. With fewer sea otters to control their numbers, sea urchins overgrazed kelp forests, leading to their degradation. This loss of kelp not only affected marine biodiversity by reducing habitat for various species but also impacted coastal fisheries and the overall health of marine ecosystems. The decline in kelp forests created a cascading effect, demonstrating the critical role sea otters play in maintaining ecological balance.

How does an increase in the Pacific Sea otter population affect the abalone population off the coast of California If the independent variable?
An increase in the Pacific sea otter population leads to a decline in the abalone population off the coast of California. Sea otters are a natural predator of sea urchins, which graze on kelp and indirectly affect the abalone population. As otters thrive and control sea urchin numbers, kelp forests can flourish, providing a better habitat for abalones. Consequently, while otter populations rise, the abalone population may initially decline due to increased predation, but over time, healthier ecosystems can support both species.
What factors affect the populations in an?
One factor that can affect the populations in an ecosystem is that, if an ecosystem had owls with no predators, the owl population would increase and eat all the mice in the ecosystems. The population of the mice would decrease more and more.
