The given statement is false.
Explanation:
In ecology, one of the means of measuring diversity is Simpson's Diversity Index. This index is generally used to count the biodiversity of a habitat. The index considers the number of the present species, and at the same time each species' abundance.
Simpson's index denoted by D determines the possibility that two characters selected abruptly from a sample will fit to a similar species or some classification other than species. When the value of D is 0, it signifies infinite diversity, while when the value is 1 it denotes no diversity. Thus, the bigger the value the lower will be the diversity.
Answer:
Index fossil that is also known as indicator fossil is used to determine the age of the layers of the rocks. It says that the new layer of sedimentary rocks lie over the old layer.
The deeper we go, the older the rocks we will find. Index fossil of animals that lived or survived only for a short period of time are very useful. An example of index fossil can be Ammonites that were found in Mesozoic era that was about 25-35 million years ago.
