snake = tertiary consumer
(hawk = quaternary consumer)

Food webs show energy flowing in many directions, so they are more realistic.

Name 2 differences between primary and secondary succession.
Any two of the following answers are acceptable.
- Primary succession happens slower than secondary succession.
- Primary succession has no remains of the older community but in secondary succession, parts of the older community exist.

Grasshoppers and squirrels eat plants.
Scorpions eat grasshoppers.
Foxes eat scorpions and squirrels.
