3n utof ztion Read the excerpt below and answer the following questions. Sea otters feed on sea urchins which are slow-moving plant-eating animals. Sea urchins threaten kelp forests because they multiply quickly and eat the roots of the kelp.

Sea otters help to control sea urchin populations minimizing their impacts on kelp forests.
