True or False: Adult fleas eat blood from mammals and their larvae eat dried blood from the feces of adults.

The statement is true because adult fleas are indeed blood-feeding parasites that require the blood of mammals for their nutrition. They feed on the blood to sustain themselves and to reproduce. This process is essential for their lifecycle, as the blood provides the necessary nutrients.

Moreover, flea larvae do not consume blood directly; instead, their diet consists of organic debris, including the dried blood and feces left behind by adult fleas. The feces act as a food source, providing the larvae with the nutrition they need to grow and develop into adult fleas.

This is a key aspect of the flea life cycle, where both life stages have adapted to utilize blood in different ways to ensure their survival and reproduction. Understanding this dynamic helps in effectively managing flea populations, especially in pest control contexts.
