What are the advantages of Bioindicators?

The advantages associated with using Bioindicators are as follows: (a) Biological impacts can be determined. (b) To monitor synergetic and antagonistic impacts of various pollutants on a creature. (c) Early stage diagnosis as well as harmful effects of toxins to plants, as well as human beings, can be monitored.

Why are frogs good Bioindicators?

Amphibians are good bioindicators of environmental pollution due to their susceptibility to chemicals during their freshwater cycles. The effects of environmental pollution, together with changes in human activity and climate, have contributed to the reduction in the amphibian population over recent decades.

Which of the following is well known example of bioindicator of air pollution?

Hence, the correct answer is option (B) Lichen. Note: Lichen is sensitive to sulfur dioxide gas. The extraordinary sensitivity of lichens to sulfur dioxide is incompletely related to their capacity to retain more sulfur dioxide for a given concentration than normal vascular plants.

Which one of the following is the well known example of bio indicator of air pollution?

The correct answer is Lichens. Lichens are a well-known example of bioindicators of air pollution.

What are biological indicators?

Biological indicators (BIs), as defined by ANSI/AAMI and ISO, are test systems containing viable microorganisms providing a defined resistance to a specific sterilization process. Endospores, or bacterial spores, are the microorganisms primarily used in BIs. They are considered some of the toughest ones to kill.

What are the 6 main indicators of water quality?

Water quality parameters include a wide range of chemical, physical and biological properties, with six principal indicators: dissolved oxygen, turbidity, pH, bioindicators, nitrate chemicals, and water temperature.

What is meant by biological indicator?
