water
nitrogen
carbon
Question 15
What can happen to bodies of water when excess fertilizers are introduced?
the dissolved oxygen levels can drop to zero
water plants and algae will die
excess nitrogen will evaporate and pollute the air
they will dry up
Nitrogen
Phosphorus
Potassium
Hydrogen
Explanation / Answer
11 nitrogen
12 oceans. 97% of the earths water is present in the oceans and then in glaciers in the form of ice
13 photosynthesis
14 nitrogen. some kind of nitrogen fixing bacteria will transform the molecular nitrogen into usable forms of nitrogen such as ammonia, nitrate and nitrite
15 the dissolved oxygen levels can drop to zero.
excess of nitrogen in ocean waters will increase the production of organisms. this results in the consumption of higher amounts oxygen by the organisms leading to depletion of oxygen
