Question

3. How do human activities such as the over-fertilizing of croplands and improper handling of animal waste (1 point)

and sewage impact the nitrogen cycle?
They cause less nitrogen to be cycled through, impacting plant growth.
They cause less nitrogen to be cycled through, impacting air pollution.
They cause more nitrogen to be cycled through, impacting aquatic ecosystems.
They cause more nitrogen to be cycled through, impacting fossil fuel production.

Answer 1

The answer is C, more nitrogen, impacting aquatic environment.

Step-by-step explanation:

This is because the extra runoff from the fertilizer will filter into aquatic systems

Answer 2

Answer:Option C

Step-by-step explanation:

The human activities such as over fertilizing affects the nitrogen cycle by the running off of the fertilizer into the nearby water bodies.

The water containing more fertilizer gives rises to the algae in the water and then it decreases the amount of oxygen in the water bodies.

There is no supply of oxygen in the water bodies for the other aquatic animals.

This causes more nitrogen to move into water and hence disturbing the aquatic ecosystem and recycling more nitrogen.
