Final answer:
Dense rainforests and mountain peaks are suitable for a camera trap as they have diverse wildlife, while open deserts and urban areas are not suitable due to lack of animal activity.
Step-by-step explanation:
The suitable places for a camera trap would be those that have a high likelihood of capturing animal activity. The dense rainforest and mountain peak are ideal locations as they are habitats for a variety of wildlife. On the other hand, an open desert would not be suitable for a camera trap as the lack of vegetation and scarce wildlife make it unlikely to capture significant animal activity. Urban areas, like cities, would also not be suitable since they are heavily populated by humans and have limited animal activity.
