Orcas, or killer whales, are natural predators of sea otters. it has been observed that in regions where the sea otters are not present, sea urchins grow rapidly and destroy much of the natural kelp vegetation. which of these statements is correct in this context? a) kelp is the keystone species because their survival is key to the survival of the entire ecosystem. b) sea otters cannot be considered the keystone species because they are not the top predators in the ecosystem. c) sea urchins are the keystone species because they multiply rapidly in the absence of their natural predators. d) sea otters are a keystone species as they prevent a herbivorous species from completely destroying a plant species.

The image above is of a kelp bed. in ideal conditions, kelp can grow up to 18 inches per day. in stark contrast to the slow-growing corals, the giant kelp canopies tower above the ocean floor. like trees in a forest, these giant algae provide food and shelter for thousands of fish, invertebrates, and marine mammal species. storms and weather events, like el niño, can tear and dislodge the kelp, leaving a tattered forest to begin its growth again each spring. sea otters and sea urchins play critical roles in the stable equilibrium of this ecosystem. sea urchins graze kelp and may reach population densities large enough to destroy kelp forests at the rate of 30 feet per month. urchins move in herds, and enough urchins may remain in the location of a former kelp forest to stop any regrowth. in the scenario above, identify the keystone and foundation species. infer what might happen if the keystone species were greatly reduced. a) keystone species is the kelp. if the kelp is reduced or destroyed the basis for the entire ecosystem is destroyed as is the ecosystem. b) keystone species is the kelp. it is the foundation for this ecosystem. if destroyed it would be replaced by another producer to establish a different ecosystem. c) keystone species is the sea otter. sea otters, playing a critical role in containing the urchin populations, prey on urchins and thus control the numbers of kelp grazers to maintain the forest. d) keystone species is the sea urchin. if the sea urchin species is greatly reduced by an increase in the sea otter population, the kelp beds would continue to grow unchecked and other populations of herbivores would grow.
