Step-by-step explanation:

Morgan fills a 1-liter jar with water from the pond.

Capacity of Jar = 1 liter

She uses a 100-milliliter cup to scoop water out of the pond and pour it into the jar.

Capacity of cup used to pour in to the Jar = 100 milliliter

We have relation

         1 liter = 1000 ml

         1 liter = 100ml x 10

         Capacity of Jar = Capacity of cup used to pour in to the Jar x 10

Number of scoops required = 10
