Those organisms which have these features: living in sessile style, high abundance, easy to culture in the lab and easy sampling, tolerating high amount of pollutants without death and occupying an important position in the food chain.
What are indicator species tell you about the environment quizlet?
the indicator species helps you determine the health the an ecosystem and the carrying capacity tells you how many species an environment can hold so all together the indicator species can dictate how large or small the carrying capacity will be.
