Eukaryotic algae are found distributed among many different groups, or major branches of the tree. Algae can be found in nearly any environment that is moist and receives enough sunlight for growth. As far as they could see there was no algae in sight, the water was one glassy blue. See More : a plant or plantlike organism of any of several phyla, divisions, or classes of chiefly aquatic usually chlorophyll-containing nonvascular organisms of polyphyletic origin that usually include the green, yellow-green, brown, and red in the eukaryotes and especially formerly included the cyanobacteria in the prokaryotes. Choose a language from the menu above to view a computer-translated version of this page. Wet soils and both fresh and salt water are usually teeming with algae.
Such blooms often take on a red or brown hue and are known colloquially as. Humans that consume the water can become very sick as well. They are most common in water, such as oceans, rivers, lakes, streams, ponds, and marshes. Colors observed are green, yellowish-brown, or red. As more algae and plants grow, others die.
That would be, of course, the algae from the air-purifying-system tanks. Many algae live and grow as single, microscopic cells. Evolution produced a fur coat made of hollow hair shafts to help insulate the polar bear against the cold, harsh environment it lives in. Blooms may also consist of non- species. I like to start with the black bears. Annual Review of Marine Science. Instead they belong to a group of living things called.
Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis. When phosphates are introduced into water systems, higher concentrations cause increased growth of algae and plants. Here in the more temperate United States, those hollow, transparent hairs have become an ecosystem of their own. Land species mostly live in moist soil and on tree trunks or rocks. Algae differ from plants in several ways. They are also capable of independently conducting nitrogen fixation, the process of converting atmospheric nitrogen to usable forms of the element such as ammonia.
Search algae and thousands of other words in English Cobuild dictionary from Reverso. Archived from on 22 August 2009. Certain algae are familiar to most people; for instance, seaweeds such as kelp or phytoplankton , pond scum or the algal blooms in lakes. However, algae are actually neither plants nor animals. Algae have a nucleus, exist as microscopic cells, and generate oxygen through photosynthesis.
Some species live in soil or on leaves, wood, and stones. Some species live in extreme environments, such as deserts, hot springs, and glaciers. Some algal blooms are the result of an excess of nutrients particularly phosphorus and nitrogen into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. Additional marine mammal species, like the highly endangered , have been exposed to neurotoxins by preying on highly contaminated. Green Polar Bears I love going to the zoo. For example, a of 107 occurred along the Florida panhandle in the spring of 2004 due to ingestion of contaminated with high levels of. Phytoplankton are the large populations of free-floating microbes found throughout the oceans.
This is clearly demonstrated in our current understanding of the tree of life — a family tree of all living organisms organized by their various evolutionary relationships. Immune system responses have been affected by brevetoxin exposure in another critically endangered species, the. Second, many algae are unicellular, according to a published in the journal Current Biology. The algae don't hurt the bear. Algae are a group of oxygenic, phototrophic, eukaryotic microorganisms.
Proceedings of the Centers for Oceans and Human Health Investigators Meeting. They are oxygenic phototrophs, meaning they use light as their energy source for growth and produce oxygen as a byproduct, like plants. However recent research found that the warming of summer surface temperatures of lakes, which rose by 0. Another large group are the dinoflagellates, made up of many diverse organisms, including phototrophic algae. In studies at the population level bloom coverage has been significantly related to the risk of non-alcoholic death.
