Algae Covered Pond. Algal nutrient solutions are made up of a mixture of chemical salts and seawater. [1] Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow.
Chara is a genus of charophyte green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures. They are found in freshwater, particularly in limestone areas throughout the northern temperate zone, where they grow submerged, attached to the muddy bottom.
Two important subclasses of lakes are ponds, which typically are small lakes that intergrade with wetlands, and water reservoirs. Over long periods of time, lakes, or bays within them, may gradually become enriched by nutrients and slowly fill in with organic sediments, a process called succession. When humans use the drainage basin, the ...
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Morgan-Peters hurried over to find a separating funnel filled with green-yellow fluid and small chunks of algae. Floating atop the thickest layer of algae was a pale yellow liquid, which Van Kley ...
In this system, algae can be cultivated in natural water bodies like lakes, rivers, and in oceans, as well as artificial ponds made up of concrete, plastic, pond liners or variety of materials. The open system of algae cultivation is simple and cost-effective, making it an attractive option for commercial production of algae-based products.
Freshwater invertebrates provide an important link in freshwater food chains, transporting the nutrients and energy from producers such as algae and aquatic plants to higher consumers such as fish and amphibians. [9] Additionally, invertebrates can act as important bio-indicators for ecosystem health. [9]
