What is phytoplankton and why are they so important?
Phytoplankton are microscopic marine organisms that sit at the bottom of the food chain. Phytoplankton get their energy from carbon dioxide through photosynthesis (like plants) and so are very important in carbon cycling. Each year, they transfer around 10 billion tonnes of carbon from the atmosphere to the ocean.

What are Phytoplankton?
Derived from the Greek words phyto (plant) and plankton (made to wander or drift), phytoplankton are microscopic organisms that live in watery environments, both salty and fresh.
Why are phytoplankton scarce in the ocean?
By contrast, phytoplankton are scarce in remote ocean gyres due to nutrient limitations.
How does phytoplankton cause mass mortality?
Phytoplankton cause mass mortality in other ways. In the aftermath of a massive bloom, dead phytoplankton sink to the ocean or lake floor. The bacteria that decompose the phytoplankton deplete the oxygen in the water, suffocating animal life; the result is a dead zone.
How do phytoplankton use photosynthesis?
Like land plants, phytoplankton have chlorophyll to capture sunlight, and they use photosynthesis to turn it into chemical energy. They consume carbon dioxide, and release oxygen. All phytoplankton photosynthesize, but some get additional energy by consuming other organisms. Phytoplankton growth depends on the availability of carbon dioxide, ...
What are the factors that affect phytoplankton growth?
Other factors influence phytoplankton growth rates, including water temperature and salinity, water depth, wind, and what kinds of predators are grazing on them.
Why does phytoplankton productivity drop?
Productivity is expected to drop because as the surface waters warm, the water column becomes increasingly stratified; there is less vertical mixing to recycle nutrients from deep waters back to the surface.
How long does a phytoplankton bloom last?
Blooms in the ocean may cover hundreds of square kilometers and are easily visible in satellite images. A bloom may last several weeks, but the life span of any individual phytoplankton is rarely more than a few days.
What is the name of the plant-like community of plankton?
plankton: Phytoplankton. The plantlike community of plankton is called phytoplankton, and the animal-like community is known as zooplankton. This convenient division... Phytoplankton populations in the oceans have been shown to rise and fall according to cycles lasting several years to decades.
What is the primary food source of all sea organisms?
Oceanic phytoplankton is the primary food source, directly or indirectly, of nearly all sea organisms. Composed of groups with siliceous skeletons, such as diatoms, dinoflagellates, and coccolithophores, phytoplankton varies seasonally in amount, increasing in spring and fall with favourable light, temperature, and minerals.

What is the role of phytoplankton in the food web?
Phytoplankton serve as the base of the aquatic food web, providing an essential ecological function for all aquatic life. Under future conditions of anthropogenic warming and ocean acidification, changes in phytoplankton mortality due to changes in rates of zooplankton grazing may be significant.
How deep does phytoplankton need to be to survive?
The depth phytoplankton operate at varies, sometimes confined just to the surface, and at other times drifting to 100 metres deep.
What happens to phytoplankton during photosynthesis?
During photosynthesis, they assimilate carbon dioxide and release oxygen. If solar radiation is too high, phytoplankton may fall victim to photodegradation. For growth, phytoplankton cells depend on nutrients, which enter the ocean by rivers, continental weathering, and glacial ice meltwater on the poles.
What is the name of the phytoplankton?
Thin layers. NAAMES. v. t. e. Phytoplankton ( / ˌfaɪtoʊˈplæŋktən /) 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'.
Why do scientists add iron to the ocean?
Large-scale experiments have added iron (usually as salts such as iron sulphate) to the oceans to promote phytoplankton growth and draw atmospheric CO 2 into the ocean. Controversy about manipulating the ecosystem and the efficiency of iron fertilization has slowed such experiments.
How do phytoplankton get energy?
Phytoplankton obtain their energy through photosynthesis, as do trees and other plants on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers ( euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations.
Why do phytoplankton have colored patches?
However, when present in high enough numbers, some varieties may be noticeable as colored patches on the water surface due to the presence of chlorophyll within their cells and accessory pigments (such as phycobiliproteins or xanthophylls) in some species.
Why are diatoms important?
Diatoms (image seen below) are an extremely important phytoplankton that while microscopic, replicate rapidly. Diatoms can be used as an indication of water quality, as they follow a “bloom-and-bust” life cycle. As nutrients reach the sunlight surfaces of an ocean, diatoms rapidly reproduce.
What is the role of dinoflagellates in coral reefs?
Dinoflagellates are an important phytoplankton typically involved in supporting coral reef ecosystems as a significant food source for many species . Dinoflagellates are known to cause harmful algae blooms exhibiting a characteristic red color, termed “red tide” (shown below). Such blooms have been known to contaminate shellfish, which will cause food poisoning in humans, if consumed.
How many species of phytoplankton are there?
Since the term phytoplankton encompasses a wide variety of different photosynthesizing aquatic microorganisms (over 5000 species recorded), different species are found in each specific environment. Examples of some of the most commonly studied species are described below:
What are the nutrients that phytoplankton need to survive?
For aquatic environments to support phytoplankton, the presence of iron, phosphate, silicic acid, and nitrate are required. Indeed, when there is a deficiency in these macronutrients, there is a corresponding absence of phytoplankton.
What is a cyanobacteria?
Cyanobacteria (pictured below) are extremely small phytoplankton that typically inhabit less turbulent waters and can thrive in environments where there are fewer nutrients available. Cyanobacterial species are highly diverse and have been shown to be extremely tolerant to changes in aquatic conditions, thus outcompeting many other types of phytoplankton when water temperatures change or nutrients become less abundant.
Why are phytoplankton colored?
Although each organism is microscopic, in sufficient numbers, phytoplankton can be observed as colored patches at the surface of bodies of water, or where two currents meet, due to the presence of chlorophyll. Phytoplankton are often cultured to support aquaculture, and are critical for controlling carbon dioxide and oxygen levels in ...
What is phytoplankton?
Phytoplankton are a type of microscopic plankton capable of photosynthesis found in oceans, seas, and freshwater, and an essential component of aquatic ecosystems. Phytoplankton can range in size and shape, and since they are photosynthesizing autotrophic organisms, they inhabit waters exposed to sunlight.
