Food chain would be:
Roadrunner (lizard-eating bird)-tertiary conusmer 0.1% of energy
Lizard and Snake –secondary consumers-1% of energy
Caterpillar and Tiger Beetle -primary consumers (herbivores)-10% of energy
Grass-primary producer (photosynthesis)-100% of energy
90% of the energy which enters in each step of the pyramid is used up by the consumers, only 10% of the energy get stored.
