Both plankton play a huge role in keeping our ocean ecosystem healthy. Most zooplankton sink towards the bottom of the ocean during the day, and at night they migrate towards the surface and feed ...

The plankton in the microlayer are distinctly adapted to withstand high levels of radiation, and serve as buffers to prevent this potentially harmful radiation from reaching the deeper water. Environmental changes such as aerosols or dust storms can cause these surface plankton to become overproductive, leading to blooms .
Coccolithophores are of interest to those studying global climate change because as ocean acidity increases, their coccoliths may become even more important as a carbon sink. [55] The most abundant species of coccolithophore, Emiliania huxleyi is an ubiquitous component of the plankton base in marine food webs. [56]
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
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'.
Seasonal changes to the environment may influence changes to migration patterns. Normal diel vertical migration occurs in species of foraminifera throughout the year in the polar regions; however, during the midnight sun, no differential light cues exist so they remain at the surface to feed upon the abundant phytoplankton, or to facilitate ...
Planktology is the study of plankton, various small drifting plants, animals and microorganisms that inhabit bodies of water. Planktology topics include primary production, energy flow and the carbon cycle. Plankton drive the "biological pump", a process by which the ocean ecosystem transports carbon from the surface euphotic zone to
