Assuming that this is a healthy ecoystem, which of the following organisms would you expect to have the smallest population?

As you go higher in a food chain/ web, there is less energy to get from each individual creature, therefor harder to sustain higher populations. This is why you will see tens of thousands of trees in a forest, thousands of insects, hundreds of birds, and some smaller predators such as foxes and skunks.
