Most phytoplankton is too small to be seen as individual cells, but when many are present, they appear as a green discoloration of the water due to the presence of chlorophyll within their cells. Zooplankton has three alternative food sources (the two phytoplankton groups and biogenic particulate material or detritus) grazed with preference that changes dynamically as a function of their relative proportion (Fasham et al., 1990). Most phytoplankton serves as food for zooplankton, but some is carried below the light zone.

that are either free-floating or suspended in the water, with little or no power of locomotion. They are divided into PHYTOPLANKTON and ZOOPLANKTON.

Phytoplankton prepares their own food by the process of photosynthesis and is called as autotrophs while zooplanktons depend on phytoplankton for their food and other matter found in the sea also called as heterotrophs.

Zooplankton aus marinen und brackigen Gewässern community structure and productivity can be affected by changes in phytoplankton.

Phytoplankton is found on the surface of the water, where there is a lot of sunlight. Zooplankton frequents the darker and cooler places in the waters. 3. Phytoplankton makes its own food through photosynthesis while zooplankton survives on other life forms in the waters. 4. Phytoplankton and zooplankton plankton are organisms found in the ocean and bodies of freshwater that drift and cannot swim against the current.In this video Qualitative study of phytoplankton and zooplankton in the upper lake of Bhopal during July 2004 to June 2005, was studied.

av KSL Johansson · 2013 · Citerat av 2 — phytoplankton and zooplankton. Zooplankton assemblages predominated by small animals feeding on low-quality resources may reduce the food quality for

Interrelationship between phytoplankton and zooplankton was observed in an artificial lake from December, 1994 to January, 1995. This lake lies in the Safari Park of Karachi. The concentration of phytoplankton remained higher than zooplankton in the surface water samples except in the autumn season while this condition was almost reversed in the depth samples. Phytoplankton are the foundation of the aquatic food web, the primary producers, feeding everything from microscopic, animal-like zooplankton to multi-ton whales. Small fish and invertebrates also graze on the plant-like organisms, and then those smaller animals are eaten by bigger ones. Zooplankton are minute animal life, including larval stages of crustaceans and other invertebrates, and tend to be larger than phytoplankton. Zooplankton are ideal for carnivores such as soft and stony coral, zoanthids, mushroom corals, anemones, shrimp and crabs.

Zooplankton Zooplankton are a diverse group that utilizes different nutrition modes such as herbivory (graze on plant matter such as phytoplankton) or carnivory (graze on animal matter such as other zooplankton). Important representatives of zooplankton include protozoans, crustaceans, copepods, euphausids (krill) and jellyfish.
