Plankton

Real World Example

Imagine you're in a crowded subway car during rush hour, trying to find your way to the exit as the train lurches and sways. Just like you, plankton are tiny microscopic organisms that float or drift in the water, carried by the currents without control over their movement. In this analogy, the subway car movement is akin to the water currents, and you, like plankton, are at the mercy of these forces, going wherever they take you without active propulsion.
