Answer to Question 1

ANS: T
The base of the food chain was killed when extremely heated water was used to blast the oil particles
off the rocks. Also, these streams of water are coming from high pressure jets. Information can be
found in the section Marine Pollutants May Be Natural or Human Generated.

Answer to Question 2

ANS: T
This method of collection takes a major toll on reefs. The species that are able to survive the poison
are taken to aquarium collectors. Unfortunately this practice will remain as long as people continue to
pay for these species. Information can be found in the section Organisms Cannot Prosper if Their
Habitat Is Disturbed.
