Question

Plant-pollinator mutualism wherein the extinction of one species invariably leads to the extinction of the other is an example of

• A. Human beings are not allowed to enter
• B. People are an integral part of the system
• C. Plants are paid greater attention than animals
• D. Living organisms are brought from all over the world and preserved for posterity

Answer 1

The correct option is A Human beings are not allowed to enter

When a species becomes extinct, the plant and animal species associated with it in an obligatory way could also become extinct. When a host fish species becomes extinct, its unique assemblage of parasites also meets the same fate. Another example is the case of a coevolved plant-pollinator mutualism wherein the extinction of one species invariably leads to the extinction of the other. This phenomenon is called co-extinction.
