An analogous organ is a trait that appears similar in unrelated organisms. It indicates that the unrelated organisms are living in similar environments and have evolved similar characteristics to deal with similar problems.
An indicator species, also known as a bioindicator, is a species that is more susceptible to environmental change, and therefore can be used to gather information about a certain environment, through their abundance or absence and their health. Lichen and Frogs are both indicator species.
E coli is often used as an indicator of bacterial contamination or of a specific type of pollution. You could use a particular species of insect as an indicator of the efficacy of an insecticide.
Will likely be affected first if any part of the ecosystems are degraded
indicator species is used for seeing the growth of animals via bacterias
birds.
Indicator organisms are organisms that are sensitive to changes in the environment. When populations of indicator species changes, it can signal a change in the environment that will eventually effect other species as well.

some are bugs
Indicator species are a useful management tool, and can help us delineate an ecoregion, indicate the status of an environmental condition, find a disease outbreak, or monitor pollution or climate change. In one sense, they can be used as an "early warning system" by biologists and conservation managers. Indicator species must also be accompanied by a thorough study of what is being indicated, what is really correlated, and how this one species fits into the rest of ecosystem.

Protozoans form sediment and are considered an indicator species.
