What is the term for an aquatic ecosystem zone where sunlight can penetrate?

What is the term for an aquatic ecosystem zone where sunlight can penetrate?

The photic zone, euphotic zone, epipelagic zone, or sunlight zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. The photic zone is home to the majority of aquatic life due to its location.

What are the zones of a freshwater biome?

Freshwater Biomes

  • The littoral zone is the water closest to shore.
  • The limnetic zone is the top layer of lake water away from shore.
  • The profundal zone is the deep water near the bottom of a lake where no sunlight penetrates.
  • The benthic zone is the bottom of a lake.

What is the shallow zone of a freshwater habitat called?

littoral zone
The littoral zone is a shallow zone in a freshwater habitat where light reaches the bottom and nurtures plants and aquatic life is diverse and abundant. Some plants are rooted in the mud underwater with their upper leaves and stems above water.

What zone receives little sunlight and is at the bottom of a body of water?

aphotic zone
There is enough sunlight for photosynthesis only in – at most – the top 200 meters of water. Water down to this depth is called the photic zone. Deeper water, where too little sunlight penetrates for photosynthesis, is called the aphotic zone.

What is another name for the photic zone?

Let’s learn them! Photic Zone is the top layer, nearest the surface of the ocean and is also called the sunlight layer.

Which of the following is the zone of a pond or lake?

Within a lake or pond, aquatic plants grow in an area known as the littoral zone–the shallow transition zone between dry land and the open water area of the lake. In Minnesota waters, the littoral zone extends from the shore to a depth of about 15 feet, depending on water clarity.

What are the three zones of freshwater?

3 Major Zones of a Freshwater Lake (With Diagram)

  • Lentic Community:
  • Lake Zonation:
  • (a) Littoral zone:

What are the three zones of freshwater ecosystems?

Three zones of fresh water ecosystem

  • limnetic zone.
  • littoral zone.
  • profundal zone…

What is the meaning of Limnetic zone?

The limnetic zone is the open and well-lit area of a freestanding body of freshwater, such as a lake or pond. Not included in this area is the littoral zone, which is the shallow, near-shore area of the water body. Together, these two zones comprise the photic zone.

What is meant by the photic zone?

photic zone, surface layer of the ocean that receives sunlight. The uppermost 80 m (260 feet) or more of the ocean, which is sufficiently illuminated to permit photosynthesis by phytoplankton and plants, is called the euphotic zone.

What is profound zone?

The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration. This is typically below the thermocline, the vertical zone in the water through which temperature drops rapidly.

What are the different zones of a freshwater lake?

Zones found in freshwater lakes include the littoral, limnetic, profundal and benthic zones. The topmost zone in a lake is the littoral zone, which is the area near the shore.

What are the different zones of the aquatic ecosystem?

Understanding different aquatic zones and how they support life. The top zone near the shore of a lake or pond is the littoral zone. The near-surface open water surrounded by the littoral zone is the limnetic zone. The deep-water part of the lake/pond, the profundal zone.

Where does most photosynthesis occur in a lake?

Most photosynthesis occurs in this part of the lake. The profundal zone is much colder and denser than the previous zones. This zone is located beyond the range of sunlight penetration. This is typically down along the thermocline, the vertical zone through which temperature drops very rapidly.
