Take a good look at the ordered list of ecological risk assessment
phases. Can you recall what's involved in each of the major parts
of risk assessment? You will be assigning one of the phases to a
variety of steps in the process.
The same phase will be the correct response to more than one component.
Read each task, then type the letter corresponding to the risk assessment
phase during which you would most likely perform the task in the
box below each step.
|
Analyze stressor
response.
|
Evaluate all
lines of evidence that support or refute the risk estimate.
