Depth Zone Categories

Clownfish (Nemo)In water as the depth increases so does the pressure, whilst at the same time the temperature, light, food supply and fish abundance decreases. These changes have effect on which types of organisms can live and grow at different depths. As the depth increases the environmental conditions change gradually.
