    Many desert ecosystems are limited by available water levels, rather than rates of radiation or temperature. Water flow in these ecosystems can be thought of as similar to energy flow; in fact, it is often useful to look at water and energy flow together when studying desert ecosystems and ecology. [3]

  5. Trophic level - Wikipedia

    en.wikipedia.org/wiki/Trophic_level

    An energy pyramid illustrates how much energy is needed as it flows upward to support the next trophic level. Only about 10% of the energy transferred between each trophic level is converted to biomass. In general, each trophic level relates to the one below it by absorbing some of the energy it consumes, and in this way can be regarded as ...
