[8][9] In this index the baseline biological integrity (its function before human influence) and the current functions of an ecosystem are measured against one another to evaluate how much of ecosystem's function has been preserved. What can the student predict about the cell with more mitochondria? In humans, routine checkup to determine the level of cholesterol is important since an abnormally high or low cholesterol levels in the blood may implicate pathological conditions. Biology. The IBI evaluates the ecosystem by utilizing biosurveys and comparing species richness, indicator taxa, hybrids, and invasive species.
IBIs are used primarily to evaluate aquatic ecosystems although the concept is applicable to measuring biological integrity in any natural ecosystem. Hint A. Stipulative definition B. Precising definition C. Explanatory definition, To introduce an unusual or unfamiliar word, to coin new words, or to introduce a new meaning to a familiar word."
