State whether the following statements are true or false. If false then rewrite the correct statement by changing the word
1-Symbiotic plants eat insects as their nitrogen requirement is not fulfilled by soil.
2-To enrich the soil farmers add fertilizers and manure to the soil.
3-Plants can absorb nitrogen in the gaseous form from air.

Answer 1

Answer:

1. True

2. True

3. False

Explanation: Plants can not absorb nitrogen directly from the air. Only nitrifying bacteria can convert gaseous nitrogen into nitrites or nitrates into the soil. Plants can absorb nitrate or nitrite from the soil via their root hairs.

Corrected statement: Nitrifying bacteria like rhizobium can absorb nitrogen in the gaseous form directly from the air.
