Answer:

is hypotonic to the protozoans

Explanation:

The constant influx of water from the outside environment of the cell tells that <u>the environment is hypotonic to the cell</u>.

<em>A hypotonic environment is one with a lower solute concentration than the cytosol. Hence, water osmotically moves from the environment into the cells of the protozoans. The water needs to constantly be removed from the cells, otherwise, they will become turgid and lyse away their contents. </em>
