phoebe observes a group of snowy egrets feeding at several locations near her home. she would like to learn what foods the egrets prefer at each location. what can phoebe infer from the data in the table?

	location 1	location 2	location 3	location 4
crawfish	8	15	20	22
fish	3	11	13	12
otter	5	2	8	4

other birds compete with the egrets for food sources at location 2
crawfish eat more fish than the egrets do at location 1
egrets that prefer crawfish are more likely to frequent location 4
egrets prefer fish to insects at location 3

Explanation:

Step1: Analyze Option 1

There is no data about other birds in the table, so we can't infer this.

Step2: Analyze Option 2

The table only shows egrets' food - intake, not crawfish's food - intake, so we can't infer this.

Step3: Analyze Option 3

At location 4, the number of crawfish eaten (22) is the highest among the four locations for crawfish. So egrets that prefer crawfish are more likely to frequent location 4.

Step4: Analyze Option 4

At location 3, the number of insects (18) is higher than the number of fish (13), so egrets do not prefer fish to insects at location 3.

Answer:

Egrets that prefer crawfish are more likely to frequent location 4.
