While watching a nature program on TV about animals in an African savanna, Sydney realized that she was seeing a food chain in action. She saw some zebras eating grass and shrubs, and then she saw cheetahs eating other zebras.

If Sydney were to draw a food chain for the environment on the nature program, to which living thing should the last arrow point?
cheetah
grass
zebra
shrubs

The last arrow should point to the cheetah since it is the top predator in the food chain.
