Answer:
Self-cleaning systems
Explanation:
Oceans are natural self cleaning systems that can get rid of any material on their own.
At some parts of the ocean, new crust are being formed. In some other part, new crustal materials are added.
When organisms in the ocean die, they decay to produce some carbon compounds which goes back to the ocean and atmosphere. Their skeletal parts goes to the bottom of the ocean where it compacts with sediments to form new sedimentary rock sequences.
When wastes from land are brought into the ocean, they can be broken down on the long run.
The ocean is self cleaning and it is an effective system as such.
Structural adaptation is Physical changes in an organism in order to survive.
