Final answer:
Risk determination assesses how likely a threat will occur, considering both the likelihood and potential consequences, and is key in forming management strategies and policies.
Step-by-step explanation:
Assessing how likely a threat will occur is known as b. risk determination. The process of risk determination involves evaluating both the likelihood of a particular threat happening and the potential consequences if it does occur. In the context of invasive species, for instance, this assessment does not only look at the species' biology, but also incorporates the potential for environmental damage, social and economic impacts, and public health issues. Factors like the feasibility of control or eradication also play a significant role in this analysis. Therefore, risk determination is a critical component in the development of management strategies and public policies.
