Ocean Zones & Ecosystems

Front

What is the intertidal zone?

Back

The intertidal zone is the area where the ocean meets the land, characterized by varying conditions of water and exposure to air.

Front

What is chemosynthesis?

Back

Chemosynthesis is the process by which certain organisms produce energy by using inorganic compounds, rather than sunlight.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What are the main ocean zones?

Back

The main ocean zones are the sunlight zone (photic zone), twilight zone (disphotic zone), and abyssal zone (aphotic zone).

Front

What is the photic zone?

Back

The photic zone, also known as the sunlight zone, is the upper layer of the ocean where sunlight penetrates, typically from 0 to 200 meters deep.

Front

What is the aphotic zone?

Back

The aphotic zone is the part of the ocean where there is little to no sunlight, characterized by high pressure and cold temperatures.

Front

How do ocean zones differ?

Back

Ocean zones differ based on the amount of light, temperature, and pressure they receive.

Front

What is the significance of the abyssal zone?

Back

The abyssal zone is significant for its unique ecosystems and organisms that have adapted to extreme conditions, such as high pressure and low temperatures.

Front

What types of organisms are found in the intertidal zone?

Back

Organisms in the intertidal zone include crabs, starfish, seaweed, and various mollusks, which can withstand changing water levels.

Front

What adaptations do organisms in the photic zone have?

Back

Organisms in the photic zone often have adaptations for photosynthesis, such as chlorophyll in plants and algae.
