Nitrogen and it’s Compounds Assignment

Plants become more susceptible to diseases and pests because

1. Of acids from the acid rain
2. Leaves becoming yellow due to leaching out of nitrogen
3. Waxy layer on leaves becoming damaged causing increased transpiration
4. Of floods

Nitrogen oxides are

1. Fertilizers
2. Pollutants
3. Used as catalysts in many industrial processes
4. An important component of nitrogen cycle

The advantages of using nitrogen fertilizers does not include

1. Soil acidity
2. Disruption of nitrogen cycle
3. Growth of river plants
4. All of the Above

Most harmful effects of Acid Rain is on

1. Aquatic plants
2. Herbs
3. Trees
4. All of the Above

The main cause of Acid Rain is

1. Nitrogen (IV) oxide
2. Nitrogen (II) oxide
3. NO
4. All of the Above

The relationship between Rhizobium and Legumes is

1. Mutualistic
2. Predator/prey
3. Competitive
4. Trophic
5. Parasitic

The conversion of nitrates to nitrogen gas by bacteria is called
