I Need help on Biology lab report HAY INUSION?

Answer 1

Are you asking what a hay infusion is?

A hay infusion is a nutrient solution made by boiling hay or dried grassy material in water and straining out the plant matter. The water has nutrients that were cooked out of the hay.

This solution is good for growing bacteria that will feed other microbes in a culture. Adding a pond water culture to a hay infusion will produce a large number of bacteria and protists in a fairly short time.
