Question

Neha went to visit her grandfather in his village. She was having a serious discussion with her fellow members regarding the productivity level of crops for the present year. She suggested her grandfather to plant crops like pulses, gram, beans, etc., for a year and then follow with regular crops to increase productivity. Why did Neha suggest growing leguminous plants.? Name the type of nutrition involved in the process. Define the type of nutrition. Give another example of this mode of nutrition. First will be marked brainliest

Answer 1

Answer:

1. Symbiosis

2. There is decreased level of minerals in the soil as the plants growing in the soil use them up and they need to be replenished.

3. It helps in replenishing nitrogen in the soil.

Explanation:

The plants that were suggested are examples of leguminous plants. A nitrogen-fixing bacteria called rhizobium lives in the root nodules of leguminous plants. This bacteria converts atmospheric nitrogen into soil nitrates ( a form which plants can use). Thus, the nutrients get replenished in the soil by growing leguminous plants.
