Bioindicators include biological processes, species, or communities and are used to assess the quality of the environment and how it changes over time.
15 Ιουλ 2019 · A chemical indicator is a substance that undergoes a distinct observable change when conditions in its solution change. This could be a color change, precipitate formation, bubble formation, temperature change, or other measurable quality.
A Biological Indicator is a detector that reveals complex conditions resulting from a combination of biotic and abiotic factors, ranging from cellular levels to ecosystems. These indicators quantify information, respond to changes over time and space, and help characterize the state of an ecosystem by detecting early modifications.
13 Οκτ 2010 · A biomonitor, on the other hand, is an organism (or a part of an organism or a community of organisms) that contains information on the quantitative aspects of the quality of the environment. A biomonitor is always a bioindicator as well, but a bioindicator does not necessarily meet the requirements for a biomonitor.
A central theme in ecology has always been the attempt to link the distributions of organisms to environmental conditions. A diverse array of biological indicators is preserved in lake sediments, either as morphological remains (e.g. diatom valves) or as biogeochemical fossils (e.g. pigments).
1 Σεπ 2023 · Chemical Indicators Definition. Chemical Indicators are those chemical substances in which their presence in chemical reactions helps us to know whether the concentration of a chemical is ideal or not. Indicators are weak bases or weak acids that change in color of the solutions to reveal the characteristics of reactants as well as reactions.
