Difference Between Photic and Aphotic Zone

In an oceanic environment, the photic zone is the zone where light can be received, it's usually from 0 to 200 m deep, but this depth can be modified by the turbidity of the water. The aphotic zone is the zone where no light is received, it goes from 200 to the bottom of the sea.

What is the difference between photic zone and Aphotic zone?

Photic zone receives sunlight which penetrates the photic zone, enabling photosynthesis. ... The aphotic zone is the portion of the ocean that does not receive sunlight. Sunlight does not penetrate this zone. Photosynthetic organisms cannot survive in this zone due to the lack of sunlight.

What is the difference between the photic zone and the Aphotic zone in an aquatic biome?

The photic zone is the upper layer of water which absorbs sunlight. The aphotic zone is the deeper layer of water which does not receive sunlight.

What is the main difference between the intertidal zone and the neritic zone?

Vocabulary Language: English ▼ English Spanish

What is unique about the Aphotic zone?

In the aphotic zone, there virtually no light from the sun (1% or less of sunlight reached this zone), so photosynthesis can not take place. Consequently there are no plants or other photosynthetic organisms in this zone.

Which pelagic zone is the deepest?

This is also known as the abyssal zone. Hadopelagic zone (deep ocean trenches, greater than 6,000m) - In some places, there are trenches that are deeper than the surrounding ocean floor. These areas are the hadopelagic zone. At a depth of over 36,000 feet, the Mariana Trench is the deepest known point in the ocean.

What are the 3 zones of the ocean?

There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone.

How deep is the photic zone?

The upper 200 meters (656 feet) of the ocean is called the epipelagic or photic zone. Sunlight penetrates this zone sufficiently to support the growth of phytoplankton and/or macro algae (i.e., plants that need sunlight to make food and survive), providing the bulk of ocean primary production (food).

Why is the Aphotic zone important?

The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems. ... At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis.

What are the littoral and benthic zones?

Littoral Zones are the topmost zone of a lake or pond while the Benthic Zones (profundal zone) are near the bottom of a lake or a pond.

Which life zone is more productive?

Which life zone is more productive, the neritic or the oceanic? Explain. The Neritic zone is more productive because rivers that contain runoff from the land flow into the neritic zone, providing nutrients for plankton.

What is common to all of the benthic zones?

The benthic zone is the lowest level of a marine or freshwater system and includes the sediment surface, the water just above it, and some sub-surface layers. ... Because of the depths it can reach, the benthic zone is often characterized by low sunlight and low temperatures (Alldredge 1988).

Which zone is the most productive zone with the most abundant life?

The neritic zone is the most productive ocean region, as it supports an abundance of living organisms.
