#[[Producer]]s - [[Organism]]s which made their own food by [[photosynthesis]].
#[[Primary Consumer]]s - [[Herbivore]]s that eat [[producer]]s.
#[[Secondary Consumer]]s - [[Carnivore]]s or [[omnivore]]s that eat the [[Primary Consumer|primary consumer]]s.

| style="height:20px; width:600px; text-align:center;" |In this '''food chain''' the grass is the first [[Trophic Level|trophic level]] (a [[producer]]). The grasshopper, pied flycatcher, skunk and vulture are all [[consumer]]s. The vulture is also the last [[Trophic Level|trophic level]] and a [[Top Carnivore|top carnivore]]. It is not an [[Apex Predator|apex predator]] because it does not hunt for [[prey]], it is a [[scavenger]].
