"ZONATION AND DISTRIBUTION PART I"
QUESTION
Are organisms distributed evenly throughout all parts of the ocean? Can each organism live in any area of the ocean?
UNDERLYING CONCEPT
Organisms are not distributed evenly throughout all parts of the ocean. Life in the ocean is most heavily concentrated in the coastal (nearshore) zones. Furthermore, every organism is limited in the area that it can inhabit. This results in a zonation of organisms, with certain species occupying certain zones. This is due to both physical and biological factors.
