Q4.17. Imagine again this hypothetical community with a single predator, two herbivores, and six primary producers. Assume the following: (1) The predator is a pure carnivore, feeding on both herbivore species but no plants. (2) Each herbivore species specializes on a single plant species. (This means some plants are not consumed.) (3) The plant species do not feed on other organisms. (4) There is no cannibalism. Use this information to calculate the connectance of the system. (Hint: To answer this, you first need to calculate the number of links in this community, which is most easily done if you sketch the food web.) Q4.18. The following diagrams depict food webs for three different communities, all of which have 10 species and 4 trophic levels. Based on just the information indicated in the diagrams, which of the three communities is most likely to be stable? Food web A Food web B Food web C None is more or less likely to be stable than the others. .
