Indicator species for clean air are organisms that are sensitive to air quality and can reflect the environmental health of an area. Common examples include lichens, particularly those from the genus Usnea, which thrive in unpolluted environments. Other indicators include certain types of mosses and the presence of sensitive bird species, like the northern spotted owl, which can indicate a healthier ecosystem. Monitoring these species helps assess the impact of pollution and overall air quality.

Rana tigrina.
There are more than two endangered species. Examples of endangered species include:Amur LeopardSiberian Tiger
Though the sensitive plant is most commonly called the TickleMe Plant, its botanical, scientific name, genus and species is Mimosa pudica.
Some examples of cooperation between species are: animals alerting each other of predators, animals eating insects off of others. Some examples of competition are: fighting for living space and resources, fighting for a mate.
Some examples of chemical species are atoms, molecular fragments, molecules, and ions. These are subjected to a chemical process or to a measurement.

The Australian Christmas beetle is nocturnal. The many species of "darkling beetles", which all belong to the family Tenebrionidae, are nocturnal. Examples are the flour beetle and the pinacate beetle.
