97% of the earth’s water is in the oceans
The importance of the Oceans:
Influence our weather and climate. (eg. El nino)
They are an important part of the water cycle (evaporation)
They generate O2 and absorb CO2
They provide us with food and resources

3. Life in the Oceans The Food pyramid of the Ocean: Primary producers
Use energy (Sunlight) to convert nutrients into organic compounds (glucose)
Nothing else on the food chain produces glucose
They are found only in the upper layers
As you move up the food pyramid/trophic levels the amount of energy available is lost (through respiration and waste).
All the species in the ocean are interdependant.
