All creatures need a source of energy to stay alive. Plants get their energy from the sun and animals get energy from eating plants or other animals. A food chain shows what eats what in a habitat.

The Producers - the cacti, shrubs and plants. The Primary Consumers – the kangaroo rat, cactus mouse, lizards, poorwill, and desert tortoise. The Secondary Consumers – the kit fox, elf owl, redtailed hawk, scorpion, roadrunner, and rattlesnake. The Scavengers –  the vulture and beetles. The Decomposers or Detrivores – mushrooms, insects and microorganisms.
