Algae ranges from single floating cells to attached seaweeds, while vascular plants are represented in the ocean by groups such as the seagrasses and the mangroves. Larger producers, such as seagrasses and seaweeds , are mostly confined to the littoral zone and shallow waters, where they attach to the underlying substrate and are still within ...
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 ...
It is the presence and relative abundance of chlorophyll that gives plants their green colour. Green algae and plants possess two forms of this pigment: chlorophyll a and chlorophyll b. Kelps, diatoms, and other photosynthetic heterokonts contain chlorophyll c instead of b, while red algae possess only chlorophyll a. All chlorophylls serve as ...
The fungus-like protist saprobes are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes. For instance, many types of oomycetes grow on dead animals or algae. Marine saprobic protists have the essential function of returning inorganic nutrients to the water.
The spores of freshwater algae are dispersed mainly by running water and wind, as well as by living carriers. [83] However, not all bodies of water can carry all species of algae, as the chemical composition of certain water bodies limits the algae that can survive within them. [83] Marine spores are often spread by ocean currents.
Phytoplankton, also known as microalgae, are plant-like organisms that provide food to a variety of ocean life -- until blooms disrupt their balance. University of Georgia researcher monitors ...
Most marine viruses are bacteriophages, which are harmless to plants and animals, but are essential to the regulation of saltwater and freshwater ecosystems. [14] They infect and destroy bacteria in aquatic microbial communities, and are the most important mechanism of recycling carbon in the marine environment.
Looking through their collected data and pondering their initial question, Van Kley said they discovered a few problems using the wastewater treatment plant's products to grow algae locally.
