Question 1.

What would happen to plants and animals on Earth if the biogeochemical cycles were disrupted and stopped? Explain by giving a few examples. Class 9

Answer:

If the biogeochemical cycles were disrupted or stopped, plants and animals would not get the essential nutrients needed for survival. The balance of nature would be disturbed, affecting all living organisms.

For example:

1. If the carbon cycle stopped, plants would not get enough carbon dioxide for photosynthesis, so food production would decrease.
2. If the oxygen cycle stopped, animals and humans would not get enough oxygen for respiration.
3. If the nitrogen cycle stopped, plants would not receive nitrogen needed for making proteins and growth, leading to poor crop production.
4. If the water cycle stopped, there would be no proper rainfall, causing droughts and shortage of water for living organisms.

Thus, disruption of biogeochemical cycles would seriously affect ecosystems and may threaten life on Earth.
