Final answer:
The correct order from highest to lowest in environmental sensitivity is integrated circuits, then computers, and finally food, making option 2 the correct answer.
Step-by-step explanation:
The question pertains to the concept of environmental sensitivity in the context of ecology and the impact of different products on the environment. Environmental sensitivity refers to how susceptible a product or process is to causing environmental damage or pollution. Typically, items that bioaccumulate toxins like PCBs or require a significant amount of resources and energy to produce and decompose should be ranked higher in terms of environmental sensitivity.
Looking at the choices given, integrated circuits would likely have the highest level of environmental sensitivity. They are part of electronic devices, which are known to contain hazardous substances and are difficult to recycle. Following this, computers would be next since they encompass integrated circuits along with other components and materials. Lastly, food should have the lowest relative impact in terms of production, especially if locally sourced and grown.
Therefore, the correct order from highest to lowest level of environmental sensitivity would be: integrated circuits > computers > food, indicating that option 2 is the correct answer.
