Some primary producers are photosynthetic bacteria which feed protozoans, which feed microinvertebrates which feed larger invertebrates and vertebrates as in aquatic ecosystems. Plants use light energy from the sun to make food. Some animals absorb water through their skin when it falls as dew and other animals, such as the kangaroo rat, can make their own water out of the food they eat. Also as Maughan makes clear, Savory does not seem to understand Deserts.

Most of the savanna areas are natural ecosystems; however, they can also be formed by the degradation of tropical forests from burning, grazing and deforestation. Hot ocean currents tends to warm winters and cold ones cool summers. The extremes resulting from abrupt changes in ozone (day to day changes greater than 20 percent) have not been considered. Detrivores, or decomposers, form yet another trophic level by scavenging or decomposing dead organic material.
