Step-by-step explanation:
Sure, here's a table showing the population of ants for each month:
| Month | Population |
|------------|------------------|
| April | 400 |
| May | 400 * 3 = 1200 |
| June | 1200 * 3 = 3600 |
| July | 3600 * 3 = 10800 |
| August | 10800 * 3 = 32400|
This table demonstrates the population growth of the ants, tripling each month, starting with 400 ants in April.
