• invasive

• engineer

• predator

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 decreases, biodiversity decreases

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