Biological indicator refer to organisms, species or community whose characteristics show the presence of specific environmental conditions. Other terms used are indicator organism, indicator plant and indicator species.
What is Bioindicator example?
A bioindicator is a living organism that gives us an idea of the health of an ecosystem. The numbers of earthworms in the soil can also be used to indicate the health of the soil. One example of a bioindicator is lichens.Jan 8, 2009
What is Bioindicator give any two examples?
Bioindicators are living organisms such as plants, planktons, animals, and microbes, which are utilized to screen the health of the natural ecosystem in the environment. They are used for assessing environmental health and biogeographic changes taking place in the environment.
What are the types of Bioindicators?
There are four main types of indicators, which are not mutually exclusive, including 1) ecosystem health assessment, 2) human effects, 3) human interventions, and 4) human health and well-being.
What are 3 examples of Bioindicators in water?

- Frogs and toads.
- Crustaceans.
- Chemical pollutants.
- In oil and gas exploration.

What animal is a Bioindicator?
Frogs are also Bioindicators of quality of environment and changes in environment. Frogs are basically influenced by changes that take place in their freshwater and terrestrial habitats. This makes them important Bioindicators of ecological quality and change.
What are good Bioindicators?
Lichens and bryophytes serve as effective bioindicators of air quality because they have no roots, no cuticle, and acquire all their nutrients from direct exposure to the atmosphere. Their high surface area to volume ratio further encourages the interception and accumulation of contaminants from the air.
What is a Bioindicator?
Bioindicators include biological processes, species, or communities and are used to assess the quality of the environment and how it changes over time. Bioindicator species effectively indicate the condition of the environment because of their moderate tolerance to environmental variability (Figure 1).
What are 5 examples of Bioindicators?
Microbial biomass, fungi, actinomycetes, lichens, as well as the population of earthworms, nematodes, termites, and ants can be used as bioindicators on account of their important role in nutrient cycling, specific soil fertility, soil development, and soil conservation (Anderson, 2003).
