The zooplankton community is an important element of the aquatic food chain. These organisms serve as an intermediary species in the food chain, transferring energy from planktonic algae (primary producers) to the larger invertebrate predators and fish who in turn feed on them.

phytoplankton

Zooplankton are the animal-like primary consumers of plankton communities. In turn, zooplankton then become food for larger, secondary consumers such as fish. Zooplankton include microscopic and macroscopic organisms.

They are single-celled organisms that conduct photosynthesis. They are thus autotrophs that make their own food from sunlight, nutrients, and carbon dioxide. Zooplankton include single-celled protists (that are sometimes referred to as microzooplankton).

Jellyfish are the largest example of holoplankton. They remain in the planktonic zone for life and can grow as large as 8 feet, with tentacles up to 200 feet.

planktivorous

The biggest fish in the sea, a baleen feeder like many of the whales, the whale shark makes sardines a regular part of his diet. Some of the other fish that eat sardines include mackerel, tarpon and sharks.

In turn, zooplankton become food for fish and other animals, which then may become food for people. There must be enough phytoplankton in the water to form the base of the food web. When there is too much plankton due to excess nutrients in the water (known as eutrophication), harmful algal blooms can result.

What do zooplankton look like? Most plankton are too small to see with the naked eye, but their beautiful shapes are revealed under the microscope. Dominant among the larger organisms are Cladocerans which swim by rowing with their large antennae in a series of jerks.

Zooplankton are microscopic invertebrate animals that swim or drift in water. They are at the base of the food chain, feeding on microscopic plants and being fed upon by aquatic insects, fish and salamanders.

Phytoplankton is a group of free-floating microalgae that drifts with the water current and forms an important part of the ocean, sea, and freshwater ecosystems. Zooplankton is a group of small and floating organisms that form most of the heterotrophic animals in oceanic environments. ‘Phyto’ refers to ‘plant-like’.

Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize. But this little bacteria produces up to 20% of the oxygen in our entire biosphere.

Abstract: The disinfection effect of Copepod of zooplankton with chlorine dioxide was compared with that of chlorine. The experimental results showed that chlorine dioxide was more effective to kill Copepod.

Plankton is composed of the phytoplankton (“the plants of the sea”) and zooplankton (zoh-plankton) which are typically the tiny animals found near the surface in aquatic environments. Like phytoplankton, zooplankton are usually weak swimmers and usually just drift along with the currents.

The most significant difference between zooplankton and phytoplankton is that zooplankton are protozoans and animals, whereas phytoplankton are photosynthetic organisms, including algae (protists), blue-green algae or cyanobacteria (bacteria), and organisms such as dinoflagellates, which do not fit neatly into a single …

Plankton has been considered as edible food for the human being in 2014 after more than 5 years of research and experiment, but actually at the moment it isn’t within everybody’s grasp. In fact it is sold wholesale at the price of 3000/4000 euro per kilo!

Yes, copepods and amphipods eat algae.
