Some scientists think that chemical compounds in plants protect plants from herbivores.
Others think that the nitrogen or water content of leaves is more important in influencing herbivore abundance. Many of the models used to predict how organisms forage or allocate energy among structures or functions assume that organisms behave optimally. Attempts to use agricultural methods developed in the temperate zone in tropical areas have largely failed. In colonies of social insects, one individual, the queen, produces many offspring. The rest of the colony members raise the queen's offspring instead of producing their own offspring.
