planktonic algae การใช้

• Oysters are filter feeders, straining planktonic algae from the water.
• Microalgae, also referred to as phytoplankton, microphytes, or planktonic algae, constitute the majority of cultivated algae.
• His major areas of research include the taxonomy of planktonic algae, haptophytes, toxic diatoms and raphidophytes.
• Larvae start out consuming planktonic algae and crustaceans, then as they metamorphose they shift to larger prey.
• Two species of marine phyto-planktonic algae were discovered, which could withstand a very high degree of radioactivity.
• The oil shale is thought to have been the result of slow deposition of planktonic algae . under anoxic conditions.
• The water chemistry is normal except for a relatively high concentration of phosphorus that promotes the growth of planktonic algae.
• Most gobies feed on small invertebrates, although some of the larger species eat other fish, and a few eat planktonic algae.
• Unlike most North American cyprinids, they feed on zooplankton, planktonic algae, and floating detritus, including rotifers, copepods, cladocerans, diatoms, and the like.
• Aquatic producers, such as planktonic algae or aquatic plants, lack the large accumulation of secondary growth as exists in the woody trees of terrestrial ecosystems.
• An abundance of planktonic algae ( or plankton bloom ) in early summer changes the water chemistry and leads to the precipitation of calcium carbonate.
• The majority of algae that are intentionally cultivated fall into the category of microalgae ( also referred to as phytoplankton, microphytes, or planktonic algae ).
• The whole food chain of the lake is based on the high population of single-celled planktonic algae present in the photic zone of the lake.
• Viruses can infect and break open bacterial cells and ( to a lesser extent ), planktonic algae ( a . k . a . phytoplankton ).
• The scientists, from Duke, Syracuse and several other institutions, examined various characteristics of the core samples, including levels of calcium carbonate, carbon isotope ratios and, perhaps most important, the types of fossilized planktonic algae found in them.
• Cannel coal ( also called " candle coal " ) is a type of terrestrial shale, which is hydrogen-rich brown to black coal, sometimes with shaly texture, composed of resins, spores, waxes, cutinaceous and corky materials derived from lacustrine planktonic algae.
• Manilal's experiments ( and the subsequent work by the British scientists ) show that such marine planktonic algae could be used to quickly and safely clean up ocean surfaces where radio-active materials have accumulated, by cultivating such algae in a specific area and later removing them from there.
• The cliffs are mainly soft white chalk with a very fine-grained texture, composed primarily of coccoliths, plates of calcium carbonate formed by coccolithophores, single-celled planktonic algae whose skeletal remains sank to the bottom of the ocean during the Cretaceous and, together with the remains of bottom-living creatures, formed sediments.
