Final answer:
The pot-bellied seahorse consumes 9 shrimp per day, which is calculated by dividing the weekly shrimp intake of 63 by the number of days in a week (7).
Step-by-step explanation:
To determine how much shrimp a pot-bellied seahorse eats per day, we need to divide the total amount it eats per week by the number of days in a week. Since a pot-bellied seahorse eats about 63 shrimp per week and there are 7 days in a week, we can calculate the daily shrimp consumption using simple division:
63 shrimp ÷ 7 days = 9 shrimp per day.
Therefore, the unit rate is that the seahorse eats 9 shrimp per day.
