Jun 22, 2020 Aquatic organisms generally fall into three broad groups: plankton, nekton, and benthos. They include phytoplankton and zooplankton. As the name implies, zooplankton are animals and phytoplankton are (or were) plants.

Phytoplankton and zooplankton

December, 2013 www.ijirs.com Vol 2 Issue 12 International Journal of Innovative Research and Studies Page 492 Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates. The two main classes of phytoplankton are dinoflagellates and diatoms. Plankton form the base of the marine food web and respond rapidly to environmental changes. Local and large-scale changes in phytoplankton biomass and zooplankton abundance (beyond natural variation) were observed over the period 1958–2002, providing a possible early warning of a wider change in the marine environment. 1. Phytoplankton are plants, while zooplankton are animals 2.

In turn, zooplankton provide food for krill and some small fish. Sudden explosive increases in phytoplankton, called "blooms," occur in the ocean when nutrient and sunlight conditions are just right. Zooplankton can also be categorized according to size: nannoplankton are unicellular animals that feed on phytoplankton and are in turn eaten by other zooplankton (5/1000 mm to 60/1000 mm); microplankton (60/1000 mm to one mm) are composed primarily of eggs and larvae, usually of invertebrates; macroplankton (over one mm) often contain large numbers of copepods, along with amphipods, cumaceans Phytoplankton are some of the Earth’s most critical organisms in the sense that they generate half of the atmosphere oxygen. More importantly, they are primary producers in the aquatic food web whereby organisms such as zooplankton feed on phytoplankton. Phytoplankton are also critical to other ocean biogeochemical cycles. Zooplankton required only 3-9s of exposure time and 6-19 J/mL of ultrasonic energy to realize a 90% reduction in survival.

Marine Phytoplankton. Zooplankton. Phytoplankton is seen in marine and fresh water and they are plant-like aquatic microbes. They are marine beings similar to birds.

The plant biomass, the phytoplankton, the zooplankton, it's what feeds the fish.

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. Main Difference. The main difference between Phytoplanktons and Zooplankton is that Phytoplanktons are a photosynthetic, microscopic organisms live in rivers, lakes, freshwater, and streams whereas Zooplanktons are small aquatic animals that also live in water bodies, but they cannot make their own food, and they are dependent on phytoplankton. phytoplankton affects the zooplankton by affecting female fertility (Ahmad et al., 2011).

SeaLifeBase Glossary

Zooplankton form a critical link in the ocean food web between phytoplankton and other marine species, and are essential to all life on Earth. We explain the different types of zooplankton, like krill, copepods and dinoflagellates. We look at their predator and prey relationships, as well as the wider risks they face. Phytoplankton.

Phytoplankton are the primary producers and form the basis of the food chain providing energy for smaller grazers.
