How would the ecosystem of the Baltic Sea (Öster Sjon) be affected if the cod (törsk) became extinct?
The cod are predatory fish so the food chain they belong to would be unbalanced. There would be too many sprat, not enough plankton. Many cod are thrown back into the sea and this has created dead zones where no living things can survive.

3. Algae prevents sunlight from reaching plants underneath so they die.
4. Decomposers breakdown the dead plants and use up much of the oxygen in the water.
5. Fish and other sea life die because there is not enough oxygen left in the water.
