In contrast to land ecosystems, dead materials and excreta in aquatic ecosystems are typically transported by water flow; finer particles tend to be transported farther or suspended longer. In freshwater bodies organic material from plants can form a silt known as mulm or humus on the bottom.
Detritivores perform the first stage of remineralization, by fragmenting the dead plant matter, allowing decomposers to perform the second stage of remineralization. [2] Plant tissues are made up of resilient molecules (e.g. cellulose, lignin, xylan) that decay at a much lower rate than other organic molecules. The activity of detritivores is ...
[1] [2] Studies have shown high protist diversity exists in oceans, deep sea-vents and river sediments, suggesting large numbers of eukaryotic microbial communities have yet to be discovered. [ 3 ] [ 4 ] There has been little research on mixotrophic protists, but recent studies in marine environments found mixotrophic protists contribute a ...
About 0.085% of the 300,000 Angiosperms believed to exist can be found in marine like environments. [1] Some examples of what plants in this kingdom exist are mosses, ferns, seagrasses, mangroves, and salt marsh plants—the last three being the three major communities of angiosperms in marine waters.
Scavengers of dead plant material include termites that build nests in grasslands and then collect dead plant material for consumption within the nest. The interaction between scavenging animals and humans is seen today most commonly in suburban settings with animals such as opossums, polecats and raccoons .
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Codium fragile subsp. atlanticum is known to have arrived in the southwest of Ireland around 1808. From there it may have spread by rafting or floating in the sea. Approximately 30 years later, it was found in Scotland. It is thought to have originally come from the Pacific Ocean near Japan.
Flowers of plants in the genus Rafflesia (family Rafflesiaceae) emit an odor similar to that of decaying meat. This odor attracts the flies that pollinate the plant. The world's largest single bloom is R. arnoldii. This rare flower is found in the rainforests of Borneo and Sumatra. It can grow to be 90 centimetres (3 ft) across and weigh up to ...
