Sub-Topic 1: MARINE HABITAT
An aquatic habitat is a body of water in which organisms live. Such organisms are called aquatic organisms e.g. fish, algae, crabs, etc.
There are three types of aquatic habitats namely,
The marine habitat is a body of salty water. It is made up of the shore and open sea. Examples are the oceans and seas.

Sub–Topic 2: MAJOR ZONES OF A MARINE HABITAT
It has two major zones
LITTORAL ZONE (Continental shelf)
This zone is sub-divided into:
Splash zone: this zone is just above the high tide mark, and is wetted by the spray from breaking wave. It has occasional moisture since it is the area where water splashes when the waves break at the shore.
Intertidal Zone: This covers the shoreline between the high and low tides. The zone is covered with water during high tide and exposed to air during low tide. This happens twice daily. The zone is exposed to wave action and has high photosynthetic activities because of abundant sunlight.
The Sub-tidal zone: This is the zone that extends over the continental shelf to a depth of about 200metres. The zone experiences more variations in temperature, water turbulence, salinity and lightning more than any other zone. It is the main site of commercial fish harvest. Its high productivity is attributed to its richness in nutrients, a large part of it being in the lighted (photic) part of the ocean.
BENTHIC ZONE (Continental slope)
This zone is characterized by:
