Flexi Says: The three zones of ponds and lakes are the littoral zone, the limnetic zone and the profundal zone. Profundal zone has scavengers.

The topmost zone near the shore of a lake or pond is the littoral zone. This zone is the warmest since it is shallow and can absorb more of the Sun's heat.
Along with water quality, it is important that the physical characteristics of a pond are appropriate for swimming. The depth of the pond can often determine if it is safe to swim. In addition, sunken trees and submerged rocks can be invisible from the surface of the water and can pose a danger to swimmers.
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.

Zone 4: Submerged Pond PlantsSubmerged pond plants grow in deeper water over 16? (40 cm) deep. They have long stems and their leaves usually (but not always) float on the surface of the water.
Typically stratified lakes show three distinct layers: the epilimnion, comprising the top warm layer; the thermocline (or metalimnion), the middle layer, whose depth may change throughout the day; and the colder hypolimnion, extending to the floor of the lake.
Lake Baikal, in Siberia, holds the distinction of being both the deepest lake in the world and the largest freshwater lake, holding more than 20% of the unfrozen fresh water on the surface of Earth. It is also the oldest freshwater lake in the world, with an estimated age of 20 million to 25 million years.
Limnology divides lakes into three zones: the littoral zone, a sloped area close to land; the photic or open-water zone, where sunlight is abundant; and the deep-water profundal or benthic zone, where little sunlight can reach.
Epilimnion. This is the upper, less dense layer of warmer water, that is readily mixed by wind. ...
Metalimnion. Also called the thermocline, this is the middle layer characterized by a steady drop in water temperature, that prevents water mixing between the epilimnion and hypolimnion. ...
