A mesophile is an organism that grows best in moderate temperature, neither too hot nor too cold, with an optimum growth range from 20 to 45 °C (68 to 113 °F). [1] The optimum growth temperature for these organisms is 37 °C (about 99 °F). [2]
They are organisms that live around sea level and can survive around the same temperatures as humans. Extremophiles are organisms that grow best in extremely cold, acidic, basic or hot environments. P. fumarii is a hyperthermophile, indicating that this organism grows best at extremely high temperatures (70–125 °C).
It has been shown that the black spruce can endure temperatures as cold as –85°, and at least as warm as 20 °C. Killer whales (Orcinus orca) are found at nearly every latitude on earth. [10] They are able to withstand water temperatures ranging from 0° to 30-35 °C. [11]
The bright colors of Grand Prismatic Spring and Yellowstone National Park, are produced by thermophiles, a type of extremophile.. An extremophile (from Latin extremus 'extreme' and Ancient Greek φιλία (philía) 'love') is an organism that is able to live (or in some cases thrive) in extreme environments, i.e., environments with conditions approaching or stretching the limits of what known ...
Microscopic algae that can tolerate extremely cold temperatures can survive in snow, ice, and very cold seawater. On snow, cold-tolerant algae can bloom on the snow surface covering land, glaciers, or sea ice when there is sufficient light. These snow algae darken the surface of the snow and can contribute to snow melt. [18]
A 2022 Outside article on heat stroke cites the highest known body temperature that a human was able to survive: “The highest body temperature measured was only 17 degrees above normal. Willie ...
The most extreme hyperthermophiles live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90 °C for survival. An extraordinary heat-tolerant hyperthermophile is Geogemma barossii (Strain 121) , [ 5 ] which has been able to double its population during 24 hours in an autoclave at 121 °C (hence its name).
Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes.
