Honey bees are a perfect example of a biological indicator, meaning that their status is a reflection of the general health of the environment.

It is possible that bee losses may be a symptom of a much greater environmental problem.

Lizards eat insects and they are food for many larger species. They play a key role in the food chain.
role of sugar in biological recognition
That would be called biological control of insects.
The biological indicator should turn from purple to yellow if spores are present after running the autoclave cycle. This indicates a sterilization failure.

I believe it is the role for something (Substance or Being) in nature So oxygen molecules will have the biological role to supply the animal's blood with oxygen
A biomarker is a substance used as an indicator of a biological state, most commonly of a disease.
A bioindicator is any of a group of species which act as a biological indicator of the health of an environment.
Helium is an inert gas and forms no compounds. It has no biological role. it is used in diving gases. Inhaled in large quantities it sis an asphyxiant.
indicator help us find out find out which molecules diffused and which didn't.... for example: starch indicator indicate starch......and.......glucose indicator indicate glucose.
It is an intermediate between fungi and lichen. It is also a biological indicator
