What organisms live in the aphotic zone of the ocean?

PHOTIC ZONE. Sunlight region near the surface of water. NEUSTON. Organisms that live on the surface of the water (photo of violet snail that feeds on the by-the-wind-sailor) CNIDARIAN. Group of organisms with radial symmetry and two body structure (polyp and medusa), and have a nerve net and stinging cells in their tentacles.

What is the importance of the photic zone in photosynthesis?

Another fact of these organisms is that they inhabit in the aphotic zone, while they migrate vertically in the photic zone in the night time. Other organisms like the tripod fish and other species stay in darkness all their lives. Euphotic Zone Organisms. Euphotic zone organisms mainly include most of the ocean fishes like sharks and rays, man o war, jelly fishes, sea …

1. What is Phytoplankton?

Ans. Phytoplanktons are marine algae that are microscopic in size. They are also known as microalgae, which is quite similar to terrestrial plants....

2. What Do You Mean By Photosynthesis Rate?

Ans. Photosynthetic rate means the capacity which is a measure of the maximum rate which indicates how it leaves and can fix the carbon during the...

3. Who are Primary Producers?

Ans. Green plants and certain types of bacteria are able to convert the inorganic matter into biomass by using energy from solar radiation or by ch...

What is the photic zone?

Definition of Photic Zone. In this zone, which is called the photic zone, here the photosynthesis rate exceeds the respiration rate. This occurs because of the abundant availability of solar energy, which acts as a great energy source for the process of photosynthesis. This process helps mainly the primary producers like the phytoplankton.

Why does photosynthesis occur in the photic zone?

This occurs because of the abundant availability of solar energy, which acts as a great energy source for the process of photosynthesis. This process helps mainly the primary producers like the phytoplankton.

How deep is the euphotic zone?

Generally, the euphotic zone extends to a depth of about 80 to 100 meters while the disphotic zone measures in depths of about 80 to 700 meters. All kinds of marine organisms are found abundantly in the photic zone, mainly in the euphotic portion. Another fact of these organisms is that they inhabit in the aphotic zone, ...

Where does most of the photosynthesis occur?

For the fact, even ninety-five percent of the photosynthesis occurs in the photic zone in the ocean. Hence, if we go deeper, beyond the photic zone, which is called the compensation point there live negligible phytoplankton due to insufficient sunlight.

What is countershading in animal science?

Countershading is done when an animal is light on its underside while dark on its upper parts. In this case, when a predator looks down at this animal it mixes with the darker waters and when a predator looks at this animal from below, the light under their belly disappears into the lighted area.

What are the plants that live in the ocean?

Plants include marine algae, plankton and surprisingly, even the mangroves can grow here. The plants modified themselves to allow them to float in the ocean. In addition to this, these plants have a special ability to carry out the process of photosynthesis and in turn, serves as a diet for the other marine animals.

What is a phytoplankton?

Ans. Phytoplanktons are marine algae that are microscopic in size. They are also known as microalgae, which is quite similar to terrestrial plants. Here they contain chlorophyll and they require sunlight to help support them live and grow. Most of the phytoplankton are buoyant and they float in the upper part of the ocean, where they can find sunlight and where the sunlight penetrates the water, in the euphotic region.
