“I am a consumer
because I eat
other animals.”
Once he has consumed the warthog the rest
of the pride will consume what is left.
Hyenas will then scavenge the leftovers.
Vultures will also remove what they can.

other animals. Decomposers will eventually
decompose the waste products from these
animals.
