Question

If all green plants of the earth are destroyed

• A. All animals shall increase in number
• B. Only herbivorous animals shall die
• C. All animals shall die ultimately
• D. Nothing shall happen to animals

Answer 1

The correct option is C All animals shall die ultimately

If all green plants of earth are destroyed, all animals shall die ultimately. Plants are present in primary trophic level. So, if the primary trophic level is destroyed, energy will not be transferred from primary to secondary trophic level. Eventually, all animals in secondary, tertiary and so on the trophic level will die ultimately.

Thus, the correct answer is 'All animals shall die ultimately.'
