What is the ocean food chain?

Back

The ocean food chain is a series of organisms each dependent on the next as a source of food. It starts with producers like phytoplankton, followed by small fish, and then larger predators like tuna and sharks.

Front

What are phytoplankton?

Back

Phytoplankton are tiny producers that live in the sunlight zone of the ocean. They are essential for the ocean food web as most ocean organisms depend on them for food.

Front

What is the Abyssal Plain?

Back

The Abyssal Plain is a flat, deep area of the ocean floor, typically found at depths of 3,000 to 6,000 meters. It is one of the ocean features.

Front

What is the Continental Shelf?

Back

The Continental Shelf is the underwater land that extends from a continent, where the ocean is relatively shallow. It is rich in marine life.

Front

What is the Continental Slope?

Back

The Continental Slope is the steeply sloping area that connects the continental shelf to the deep ocean floor.

Front

What is the Continental Rise?

Back

The Continental Rise is the area at the base of the continental slope where sediments accumulate, leading to a more gradual slope.

Front

What are ocean tides?

Back

Ocean tides are the regular rise and fall of sea levels caused by the gravitational pull of the moon and the sun.

Front

What are ocean currents?

Back

Ocean currents are large-scale movements of water within the oceans, driven by factors like wind, water density differences, and the Earth's rotation.

Front

What is the Sunlight Zone?

Back

The Sunlight Zone is the upper layer of the ocean where sunlight penetrates, allowing photosynthesis to occur. It is home to most marine life.

Front

What is zooplankton?

Back

Zooplankton are tiny animals that drift in the ocean and feed on phytoplankton. They are an important part of the ocean food web.
