Which of the following organisms is considered as bioindicator of water pollution?

Key Points

• Frogs are considered bioindicators of water pollution due to their permeable skin, which makes them highly sensitive to changes in their environment.
• The presence or absence of frogs in a water body can provide valuable information about the ecological health of the area.
• Frogs are often used in environmental monitoring programs to assess the impact of pollutants, including pesticides, heavy metals, and other toxic substances.
• Their lifecycle, which includes both aquatic and terrestrial stages, allows them to reflect the health of both water and land ecosystems.

Additional Information

• Bioindicators are organisms used to monitor the health of an environment or ecosystem. They can indicate the presence of pollutants or other changes in environmental conditions.
• Besides frogs, other bioindicators of water quality include certain species of fish, macroinvertebrates, and algae.
• Using bioindicators is a cost-effective and efficient method for monitoring environmental health compared to chemical analysis methods.
• Conservation efforts often focus on protecting bioindicator species as they play crucial roles in maintaining the balance of their ecosystems.
