dangina [55]

Answer:

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.

Pachacha [2.7K]

Answer:

a prezygotic barrier

Explanation:

Both wild tigers and lions are said to be reproductively isolated.

Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.

The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.

Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.

<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>
