Which lake zone produces the most oxygen?
Which lake zone produces the most oxygen? In most lakes, phytoplankton, tiny floating plants, provide most of the oxygen production as their populations are very dense in the limnetic zone.
What zone is the deepest part of a lake?
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.
What is the lowest zone of a lake?
The Benthic Zone is the bottom of the pond or lake and consists of organic sediments and soil. As the body of water ages, this zone will increase. It is considered the pond or lake's digestive system. This zone is where bacteria decompose organic matter from dead algae, aquatic plants, and fish and animal waste.
What are the 4 zones of a lake?
So, the four zones of a lake are: the nearshore or littoral zone, open water or limnetic zone, deep water or profundal zone, the benthic zone or lake floor. The different conditions, such as the amount of light, food, and oxygen in each of the lake zones, affect what kind of organisms live there.
