Detailed Solution

Protozoans while obtaining nutrients through phagocytosis engulf their food in a vacuole and then digest it internally using lysosomal enzymes. The resulting nutrients are then absorbed across the cell membrane.

The process of phagocytosis is important for protozoans as it allows them to obtain a variety of nutrients from their environment, even in the absence of a digestive system. This feeding strategy is particularly useful in aquatic environments where food sources can be scarce and irregular.
