Food chain which connects algae to alligator

An option could be;

First, you start with

1. your primary producer (algae)

2. Primary consumer (zooplankton)

3. secondary consumer (any small fish really)

4. Tertiary Consumer (Alligator)

You can transfer this into a food web by just adding more animals that fit the list (aka eat each other)
