Q3 of 62 Page 110

Discuss one example, based on your day-to-day observations, showing how loss of one species may lead to the extinction of another.

One such example is of plant pollinator relationship. In this case if either one of them gets extinct it results in the ultimate extinction of the other, this phenomenon is called co-extinction.

Hence, when a species become extinct, the plant and animal species associated with it in an obligatory manner also become extinct.
