Answer (1 of 8): 1. hey, can be found in places with anoxic conditions like anoxic sediments, animal digestive tracts, underwater hydrothermal vents, and wastewater treatment plant sludges. The chemosynthetic bacteria grow into a thick mat which attracts other organisms such as amphipods and copepods which graze upon the bacteria directly. Thermophiles. She has a Bachelor of Science in Biology and a Master of Education. Archaea are of three type; methanogens, thermophiles, and halophiles. Animal digestive tracts: Rumen of cows, sheep, camels, and others, the large intestine of monogastric animals, and Cellulolytic insects' (termites) intestines. They use methyl group-containing compounds to produce methane. " Although some halophilic bacteria and eukaryotes exist, the largest classification of halophiles is in the Archaea domain. Methanogens are considered one of the most diverse groups in the archaea domain, with over 50 species, each with its own unique characteristics. Extreme thermophiles thrive in very hot environments. I feel like its a lifeline. Some micro-organisms grow even at more high temperature, the optimum between 80C and about 113C, and are called hyper-thermophiles. majority of them are in warm coastal waters; few are unicellular most are multicellular; are typically soft bodied but some have cell walls encrusted with hard chalky deposits; contribute to the structure of coral reefs; grass green chloroplasts; include unicellular and colonial species as well as multicellular seaweeds; Volvox is a colonial green algae. Bacterial _____ are at work in the slimy feel of an underwater rock, ear infections, and dental plaque. They are similar to osmophiles, but they grow in places with high salt concentrations. The plants and microbes of the wetland will absorb many of the contaminants that remain in the water. Some of these substrates are released by other organisms and used by methanogens. 16 What are classification of bacteria? 13 How do you classify a prokaryotic cell?

She has a Bachelor of Science in Biology and a Master of Education. When water temperature and salinity changes occur, the cysts rehydrate and releases the first growth stage, known as nauplius larva. Brine shrimp can be found in a wide range of water salinities. Methanogens, thermophiles, and halophiles are some of the most primitive forms of life found on Earth and thrive in very harsh environments. They are chemoorganotrophs (a primary nutritional group), getting their energy from oxidation (the interaction between oxygen molecules and other substances) and reduction reactions using organic sources, and are facultative anaerobes (an organism that can use oxygen but also has anaerobic (any organism that does not require oxygen for growth) methods of energy production, however, it can survive in either environment). This is also a problem because methane is released into the atmosphere and contributes to the global warming phenomenon. Methanogens, extreme halophiles, and extreme thermophiles are examples of _____. John David Jackson, Patricia Meglich, Robert Mathis, Sean Valentine. They have a short bar shape. Methanogens are organisms that produce methane as a metabolic by-product under anoxic conditions. Eukarya Domain: contains five kingdoms, which are Animalia, Plantae, Fungi, Protozoa, and Chromist. In fact, the very name "halophile" comes from the Greek word for "salt-loving. In its active feeding stage, it is a single giant multinucleate cell that slides over moist organic matter, engulfing food particles as it grows. A prokaryote collected from a hot spring in Yellowstone National Park provided scientists with a key protein for the polymerase chain reaction (PCR). Excessive current or voltage can destroy the diodes in a power supply. Barophiles. Which option provides evidence for the role of endosymbiosis in the origin of eukaryotes?
