Also know as the seashore, it is the area above water level at low tide and underwater at high tide. This area can include several types of habitats with various species of life such as starfish sea urchins.
Coral reef
Underwater ecosystem characterised by its reef building corals.
Photosynthesis
When green plants and micro organisms transform light energy into chemical energy. It is the main reason for the oxygen content on earth.
Algae
organisms in the ocean that have the ability to photosynthesise.
Plankton
Underwater organism that is used as a food source to many of the animals in the ocean
Estuary
Where fresh water meets salty water typically in mouth rivers form estuaries.
Spawn

Wetland
Eco system flooded by water either permanently or seasonally, where oxygen free processes prevail
