Question

If all green plants of the earth destroyed
(a) All plants shall die
(b) Only herbivorous animal shall die
(c) All animal shall die ultimately
(d) Nothing shall happen to the animal

Answer 1

Hint: Plants play an important role in the existence of living beings on earth. Without plants, life can't be sustained. Most importantly, they take in ${ CO }_{ 2 }$ exhaled by us and on the other hand, give us pure ${ O }_{ 2 }$ for our survival and make the atmosphere fresh.

Complete answer:
On the off chance that all green plants of earth are demolished, all creatures will die eventually. In an ecological pyramid, green plants are present at the base of the pyramid. They are present at the primary trophic level. So, if the primary trophic level is destroyed, energy will not be transferred from the primary to secondary trophic level. Eventually, all animals in secondary, tertiary, and so on the trophic levels will die ultimately.

Additional information: These are things which will occur if trees were no there:
- Excess carbon dioxide which is noticeable all around is consumed by trees and gives us oxygen. So we need to purchase oxygen gas chambers with the goal that we can inhale if trees are not there.
- If trees are not there, the temperature will rise. Trees cool the atmosphere by ${ 5^\circ - 10^\circ }{ F }$, by concealing our homes and roads and delivering water fume into the air through leaves.
- More odds of soil disintegration if trees are not there. They help to forestall soil disintegration on slopes or inclines
So the correct answer is ‘All animals shall die ultimately’.

Note: Advantages of Plants:
- Provide food to herbivores of the food chain.
- Absorb sunlight for the photosynthesis process.
- Absorb ${ CO }_{ 2 }$ and release ${ O }_{ 2 }$ as part of the Photosynthesis process.
- Cool the surrounding area.
- Shelter for birds & small animals.
Without sufficient trees
- Food is not available for herbivores, affecting carnivores & the entire food chain.
- A high level of ${ CO }_{ 2 }$ increases the global warming effect.
- Untimely rains/floods/Droughts - Monsoons will be affected.
- Many birds & animals will become homeless
