Plankton are the building blocks of life in the sea. Everything depends on them. ... called amphipods and isopods. Most of these are considered macroplankton due to their size (from ¾ of an inch ...
Phytoplankton (/ ˌ f aɪ t oʊ ˈ p l æ ŋ k t ə n /) are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems.The name comes from the Greek words φυτόν (phyton), meaning 'plant', and πλαγκτός (planktos), meaning 'wanderer' or 'drifter'.
Holoplankton can be contrasted with meroplankton, which are planktic organisms that spend part of their life cycle in the benthic zone. Examples of holoplankton include some diatoms , radiolarians , some dinoflagellates , foraminifera , amphipods , krill , copepods , and salps , as well as some gastropod mollusk species.

As plankton are rarely fished, it has been argued that mesoplankton abundance and species composition can be used to study marine ecosystems' response to climate change. This is because they have life cycles that generally last less than a year, meaning they respond to climate changes between years.
The study of the dispersion of these particles is called aerobiology. Aeroplankton is made up mostly of microorganisms , including viruses , about 1,000 different species of bacteria , around 40,000 varieties of fungi , and hundreds of species of protists , algae , mosses , and liverworts that live some part of their life cycle as aeroplankton ...
Plankton can be divided into producers and consumers. The producers are the phytoplankton (Greek phyton = plant) and the consumers, who eat the phytoplankton, are the zooplankton (Greek zoon = animal). Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally, jellyfish have been viewed as trophic dead ends.
