Data from a Burger et al. (2004) indicate that mercury levels in Florida gar, top-level predators, from Lake Okeechobee were not higher than mercury levels of fish muscle from other locations in the United States. However, mercury levels in the livers of Florida gar were above the level considered safe for human consumption

a. Explain why this is good news for people who fish in Lake Okeechobee

b. Explain why this is bad news for non-human consumers of fish, and how it might be bad news for the ecosystem as a whole.

Explanation:

As w = 2000π

2πf= 2000π

f= 1000Hz

speed = wavelength × f= w/k

wavelength = 2000π/ (0.5× 1000)

= 4π

or

12.57
