• Fertilizers

• Irrigation

Chemicals that add nitrates and phosphorus to the soil are called...

• Fertilizers

• GMOs

The build up of toxins in an animal over time is called...

• Bioaccumulation

• Biomagnification

• Eutrophication

• Tragedy of the Commons

When the concentration of toxins increase when going from one trophic level to another, that is called...

• Bioaccumulation

• Biomagnification

• Tragedy of the Commons

• Eutrophication

At what level will you expect to see the highest concentration of toxins?

• Apex predator

• Producer

• Primary consumer

• Secondary consumer

The event where bodies of water are covered in algae as a result of too much nitrogen and phosphorus is called...

• Eutrophication

• Tragedy of the Commons

• Bioaccumulation

• Biomagnification

Causes for eutrophication can include... (pick all that apply)

• Using too much fertilizer

• Animal waste washed off from farms

• Factory pollution

• Oil spills

Consequences of eutrophication include... (pick all that apply)

• Suffocation of animals from lack of oxygen

• Underwater plants can't photosynthesize

• The water in lakes and oceans is cleaned

• The rate of photosynthesis rises permanently

What is one way you can genetically modify crops?

• You selectively cross two parents with the traits you prefer (e.g. large fruits)

• You leave the crops alone and let them reproduce naturally

• You add more pollinators to increase reproduction.

• You add fertilizer to the soil to encourage growth.
