121Detritus — For other uses, see Detritus (disambiguation). In biology, detritus is non living particulate organic material (as opposed to dissolved organic material). It typically includes the bodies or fragments of dead organisms as well as fecal material.… …
122Optimal foraging theory — Ants dismember a larger insect. Optimal foraging theory predicts these insects will forage in such a way as to maximize their colony s energy intake per unit time. Optimal foraging theory is an idea in ecology based on the study of foraging… …
123Microbial intelligence — (popularly known as bacterial intelligence) is the intelligence shown by microorganisms. The concept encompasses complex adaptive behaviour shown by single cells, and altruistic and/or cooperative behavior in populations of like or unlike cells… …
124Lithotroph — A lithotroph is an organism that uses an inorganic substrate (usually of mineral origin) to obtain reducing equivalents for use in biosynthesis (e.g., carbon dioxide fixation) or energy conservation via aerobic or anaerobic respiration.[1] Known… …
125Organotroph — An organotroph is an organism that obtains hydrogen or electrons from organic substrates (a form of a chemotroph). Antonym: Lithotroph See also Lithotroph Heterotroph Primary nutritional groups …
126Microecosystem — Microecosystems can exist in locations which are precisely defined by critical environmental factors within small or tiny spaces. Such factors may include temperature, pH, chemical milieu, nutrient supply, presence of symbionts or solid… …
127Chemoorganotroph — Chemoorganotrophs are organisms which use organic compounds as their energy source. These organic chemicals include glucose and acetate. All animals are chemoorganotrophs, as are fungi, protozoa, and some bacteria. Indeed, most heterotrophs are… …
128Depensation — In population dynamics, depensation is the effect on a population (or stock) whereby, due to certain causes, a decrease in the breeding population (mature individuals) leads to reduced survival and production of eggs or offspring. The cause may… …
