Zooplankton populations often consist of copepods, cladocerans, and rotifers occurring in the open water of lakes. Most limnetic communities will consist of one dominant species of copepod, one dominant cladoceran, and one dominant rotifer. [6]
D. pulicaria are filter-feeders with a diet primarily consisting of algae, including Ankistrodesmus falcatus, and they can be found in deep lakes located in temperate climates. [3] Furthermore, D. pulicaria are ecologically important herbivorous zooplankton, which help control algal populations and are a source of food for some fish. [4]
Zooplankton feed on bacterioplankton, phytoplankton, other zooplankton (sometimes cannibalistically), detritus (or marine snow) and even nektonic organisms. As a result, zooplankton are primarily found in surface waters where food resources (phytoplankton or other zooplankton) are abundant. Zooplankton can also act as a disease reservoir.
Lake ecosystems can be divided into zones. One common system divides lakes into three zones. The first, the littoral zone, is the shallow zone near the shore. [5] This is where rooted wetland plants occur.

Zooplankton and salps play a large role in the active transport of fecal pellets. 15–50% of zooplankton biomass is estimated to migrate, accounting for the transport of 5–45% of particulate organic nitrogen to depth. [40] Salps are large gelatinous plankton that can vertically migrate 800 meters and eat large amounts of food at the surface.
Dymaxion world map with the 15 largest lakes roughly to scale. This is a pair of lists of terrestrial lakes with a surface area of more than approximately 3,000 square kilometres (1,200 sq mi), ranked by area, [1] [2] [3] excluding reservoirs and lagoons. The area of some lakes can vary considerably over time, either seasonally or from year to ...
