Ocean Zones and Phytoplankton

Front

What are the main ocean zones?

Back

The main ocean zones are the intertidal zone, neritic zone, oceanic zone, benthic zone, and abyssal zone.

Front

What is phytoplankton?

Back

Phytoplankton are microscopic plants that live in the ocean and perform photosynthesis, forming the base of the marine food web.

How do hydrothermal vents contribute to ocean ecosystems?

Back

Hydrothermal vents provide energy through chemical reactions, supporting unique ecosystems that do not rely on sunlight.

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms convert carbon molecules (usually CO2) and nutrients into organic matter using the oxidation of inorganic molecules as a source of energy.

Front

What is ocean acidification?

Back

Ocean acidification is the decrease in pH levels of the ocean caused by the absorption of excess carbon dioxide from the atmosphere.

Front

What is the role of zooplankton in the ocean?

Back

Zooplankton are small animals that drift in the ocean and are a crucial part of the marine food web, feeding on phytoplankton and serving as food for larger animals.

Front

What is the intertidal zone?

Back

The intertidal zone is the area of the shoreline that is exposed to air at low tide and submerged at high tide.

Front

What is the benthic zone?

Back

The benthic zone is the lowest ecological zone in the ocean, consisting of the ocean floor and the organisms that live there.

Front

What is the neritic zone?

Back

The neritic zone is the shallow part of the ocean that extends from the low tide mark to the edge of the continental shelf.

Front

What is the abyssal zone?

Back

The abyssal zone is the deep ocean area, typically found at depths of 2000 meters or more, characterized by high pressure and low temperatures.
