Q

What are the Laws of Thermodynamics? (2)

A

1) Energy (while transferring) can be changed. It cannot be created or destroyed.

2) Energy will be lost while transforming. This will most likely be thermal energy. However, there is energy which cannot be used.

Q

Why are the top of the food chain at risk for Bioamplification?

A

The concentration is more concentrated due to their prey having high amounts of that certain pesticide.

26
Q

What are the benefits of Pesticides?

A

Easy application, kills intended pest, and hard to trace.

27
Q

Why do pesticides come in low doses?

A

The intended pest can develop immunity in their population.
