sea otters are removed from the kelp forest ecosystem, sea urchins will be able to live and reproduce with no main predator. Whole “herds” of sea urchins have been known to sweep across the ocean floor, gobbling kelp stands at a rate of up to 30 feet per month and leaving barren sea floor in their wake. Once barren, the entire kelp forest ecosystem is destroyed and can no longer support the diversity of life once found there. The EVIDENCE above supports the CLAIM that which animal along the Central California coast is considered a keystone species?
