Kelp Forest Notes

Sea otters control the sea urchin population

Sea otters tie themselves to the kelp forest

Sea otters live in the kelp forest

Sea otters do not help the kelp forest

Predation

Mutualism

Commensalism

Parasitism

The sea urchin population rises

The kelp population drops

The kelp gets eaten more quickly than it can regrow

All of the these

Absorb carbon dioxide from the atmosphere

Filter pollutants out of the water

Provide breeding grounds for many species

Absorb oxygen from the atmosphere

Overfishing reduces the populations of many fish species

Fishing practices (trawling) are damaging the kelp forests

Dumping sediment near shore

Recreational activities are damaging the kelp forests

New regulations will require commercial fishing to be done further from shore

New kelp forests will be planted

New fish species will be brought into the area

Nothing can be done to help the kelp forests
