life: A status given to any entity with the properties of reproduction and metabolism, includingДЄnimals, plants, fungi, bacteria, and archaea (single-celled microorganisms).ДЄn organism is a living system capable of growth, reproduction,metabolism, response to stimuli, adaptation and homeostasis.Д¬ells are the basic unit of life that can be found in every living organism.В Organisms can be unicellular or multicellular and include plants, animals, bacteria, archaea, and fungi.organism: A contiguous living system that can metabolize, grow, respond to stimuli, reproduce, and adapt to its environment.extremophile: A microorganism that can survive in extreme environmental conditions.

These include carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur-the elemental macronutrients for all organisms-often represented by the acronym CHNOPS. All life forms require certain core chemical elements for biochemical structure and function.Extremophiles can survive exposure to such conditions for weeks, months, years, or even centuries. Organisms called extremophiles can assume forms enabling them to withstand freezing, dehydration, starvation, high levels of radiation, and other physical or chemical challenges.Migration and hibernation are two examples of these adaptations. Organisms cannot perform these functions as well or at all outside of these conditions, but some organisms have developed ways to adapt to environmental changes. Living organisms have ranges of ecosystem conditions where they can perform all physiological functions of life.The nonliving (abiotic) components of an ecosystem include energy, oxygen, water, nutrients, and temperature.Nonliving things are either living things that have died or inanimate objects that were never alive.Living organisms are systems made from cells and are capable of life functions such as reproduction, metabolism, response to stimuli, and homeostasis.
