Explanation:

The energy comes from the sun, the producers as the first trophic level (carrots, grasses,grains) capture the energy from solar radiation. The primary consumers (Rabbits, mice, grasshoppers) eat the producers. The primary carnivores or secondary consumer (birds)  feed  of a number alternative organism of the lower trophic levels.  The terciary consumers predate secondary consumer (owls and foxes). Finally the detritivoures feed exclusively on the dead bodies of animals and plants.
