The marine biome is divided into four main zones, each with distinct characteristics and ecosystems. These zones are:
- Intertidal Zone: This is the area where the ocean meets the land. It is exposed to air during low tide and submerged during high tide. Organisms here must adapt to changing conditions, such as temperature fluctuations and wave action.
- Pelagic Zone: Also known as the open ocean, this zone is further divided into the epipelagic, mesopelagic, bathypelagic, and abyssopelagic zones. It is characterized by its vast, open waters and is home to a wide variety of marine life, including fish, whales, and plankton.
- Benthic Zone: This zone includes the ocean floor and the sediment surface. It is inhabited by organisms such as crabs, sea stars, and worms, which are adapted to life on or near the seabed.
- Abyssal Zone: This is the deepest part of the ocean, characterized by extreme pressure, low temperatures, and complete darkness. Despite these harsh conditions, it is home to unique organisms like deep-sea fish, giant squid, and bioluminescent creatures.
Each of these zones plays a crucial role in the marine ecosystem, supporting a diverse range of life forms and contributing to the overall health of the ocean.
