Zooplankton

Real World Example

Imagine you're at a crowded party, trying to navigate through a sea of people to get to the snack table. Just like you maneuver between groups of party-goers, zooplankton drift and float through vast ocean currents among other marine organisms. The connection here is that, much like you moving with the flow of the crowd to reach your destination, zooplankton ride the ocean currents, traveling and feeding as they go, with their direction largely determined by the surrounding water movement.
