Phytoplankton are the primary producers of their ecosystem, since they are the first organisms to produce energy, which they create from light sources, such as the Sun. Energy not used by the phytoplankton for maintenance is available as food for the animals that consume it.Phytoplankton - Phytoplankton are microscopic plants that obtain their energy via photosynthesis. However, some species of bacteria are also capable of Many factors can affect the distribution of plankton in an ecosystem, which has a detrimental effect on the rest of the ecosystem because, as...Being in the category of plants, Phytoplankton releases oxygen in the atmosphere. In most marine and freshwater environments, Phytoplankton (photosynthetic prokaryotes and eukaryotic organisms) forms the basis of primary production. Difference Between Ecosystem and Community.Phytoplankton are so small that you need a microscope to see them. Types of phytoplankton include dinoflagellates, diatoms, cyanobacteria and green © Uwe kils / Wikimedia. What is plankton's role in the ecosystem?

Freshwater Communities & Plankton - Biology Online Tutorial

yes phytoplankton are member of the ecosystem. Explanation: In a balanced ecosystem, they provide food for a wide range of sea creatures. Phytoplankton, also known as microalgae, are similar to terrestrial plants in that they contain chlorophyll and require sunlight in order to live and grow.Phytoplankton accounts for half of all the photosynthetic activity throughout the world and is the primary producer in the freshwater and marine food chains. Zooplanktons are the indicators of toxic substances present in the ecosystems and also serve as food for higher heterotrophs. Examples.Phytoplankton /ˌfaɪtoʊˈplæŋktən/ are the autotrophic components of the plankton community and a key factor of oceans, seas and freshwater basin ecosystems. The name comes from the Greek words φυτόν (phyton), meaning "plant", and πλαγκτός (planktos), meaning "wanderer" or "drifter".Species composition plays a key role in ecosystem functioning. Theoretical, experimental and field studies show positive effects of biodiversity on Phytoplankton used resources more efficiently in warmer waters and at greater upwelling intensity, although these effects were not as strong as those...

Difference Between Phytoplankton and Zooplankton... - Bio Differences

Phytoplankton are the plants which grow in ocean. Their growth is exactly like most land plants. They take energy from sunlight, consume carbon dioxide Phytoplankton produce food for many sea living organisms like whale, jellyfish, snails, and shrimp. It means, in an ecosystem they act as producers.Phytoplankton plays a significant role in global ecology and ecosystem functioning. Since phytoplankton are primary producers living in a dispersive environment, abiotic physico-chemical factors exert a strong control on the composition and dynamics of phytoplankton communities.Phytoplankton affects the ecosystem of the entire earth in the sense that phytoplankton is at the very top level of the food chain. Fish and whales eat phytoplankton for energy and then we eat fish for energy.This flashcard is meant to be used for studying, quizzing and learning new information.

Geography, oceanography, and topography

The shape of the oceans and seas of the arena has modified significantly all over the previous six hundred million years. According to the theory of plate tectonics, the crust of the Earth is made up of many dynamic plates. There are two types of plates—oceanic and continental—which float at the surface of the Earth's mantle, diverging, converging, or sliding in opposition to one every other. When two plates diverge, magma from the mantle wells up and cools, forming new crust; when convergence happens, one plate descends—i.e., is subducted—under the opposite and crust is resorbed into the mantle. Examples of both processes are seen in the marine surroundings. Oceanic crust is created alongside oceanic ridges or rift areas, which are vast undersea mountain ranges such as the Mid-Atlantic Ridge. Excess crust is reabsorbed alongside subduction zones, which in most cases are marked through deep-sea trenches such because the Kuril Trench off the coast of Japan.

The form of the sea is also altered as sea levels change. During ice ages a higher share of the waters of the Earth is sure in the polar ice caps, ensuing in a fairly low sea degree. When the polar ice caps soften during interglacial periods, the sea level rises. These adjustments in sea degree reason nice changes in the distribution of marine environments corresponding to coral reefs. For example, during the last Pleistocene Ice Age the Great Barrier Reef did not exist because it does today; the continental shelf on which the reef now is found was above the high-tide mark.

Marine organisms are now not disbursed lightly all the way through the oceans. Variations in characteristics of the marine environment create other habitats and influence what sorts of organisms will inhabit them. The availability of sunshine, water depth, proximity to land, and topographic complexity all impact marine habitats.

The availability of light impacts which organisms can inhabit a undeniable area of a marine ecosystem. The larger the intensity of the water, the fewer gentle can penetrate until beneath a undeniable intensity there is not any light in any respect. This space of inky darkness, which occupies the good bulk of the sea, is known as the aphotic zone. The illuminated region above it is called the photic zone, inside of which are prominent the euphotic and disphotic zones. The euphotic zone is the layer closer to the outside that receives sufficient mild for photosynthesis to happen. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiratory exceed those of photosynthesis. The actual depth of those zones will depend on local prerequisites of cloud quilt, water turbidity, and ocean surface. In normal, the euphotic zone can extend to depths of eighty to one hundred metres and the disphotic zone to depths of eighty to 700 metres. Marine organisms are in particular considerable in the photic zone, especially the euphotic portion; alternatively, many organisms inhabit the aphotic zone and migrate vertically to the photic zone every night. Other organisms, such because the tripod fish and a few species of sea cucumbers and brittle stars, remain in darkness all their lives.

Marine environments can be characterized widely as a water, or pelagic, environment and a backside, or benthic, setting. Within the pelagic atmosphere the waters are divided into the neritic province, which includes the water above the continental shelf, and the oceanic province, which contains all the open waters beyond the continental shelf. The high nutrient ranges of the neritic province—as a result of dissolved fabrics in riverine runoff—distinguish this province from the oceanic. The higher portion of both the neritic and oceanic waters—the epipelagic zone—is the place photosynthesis happens; it's kind of equivalent to the photic zone. Below this zone lie the mesopelagic, ranging between 2 hundred and 1,000 metres, the bathypelagic, from 1,000 to 4,000 metres, and the abyssalpelagic, which encompasses the inner most parts of the oceans from 4,000 metres to the recesses of the deep-sea trenches.

The benthic surroundings additionally is split into different zones. The supralittoral is above the high-tide mark and is generally now not underneath water. The intertidal, or littoral, zone levels from the high-tide mark (the maximum elevation of the tide) to the shallow, offshore waters. The sublittoral is the environment beyond the low-tide mark and is steadily used to refer to substrata of the continental shelf, which reaches depths of between a hundred and fifty and three hundred metres. Sediments of the continental shelf that affect marine organisms usually originate from the land, particularly in the form of riverine runoff, and include clay, silt, and sand. Beyond the continental shelf is the bathyal zone, which occurs at depths of a hundred and fifty to 4,000 metres and comprises the descending continental slope and upward push. The abyssal zone (between 4,000 and six,000 metres) represents a considerable portion of the oceans. The deepest region of the oceans (greater than 6,000 metres) is the hadal zone of the deep-sea trenches. Sediments of the deep sea essentially originate from a rain of dead marine organisms and their wastes.
