Based on the graph shown, how can you tell sea otters are a keystone species?

• as the sea otter population decreases, biodiversity increases
• as sea otter population increases, biodiversity increases
• changes in the sea otter population have little effect on biodiversity 
• the sea otter population dereases due to the presence of urchins
