which term describes what is happening in the amount per trial vs. time graph?
a negative amount is eaten.
a changing amount is eaten.
nothing is consumed.
a constant amount is eaten.

Explanation:

Step1: Analyze Option A

The graph shows the amount consumed starting from 1 and increasing. There's no negative amount (since amount can't be negative in this context), so A is incorrect.

Step2: Analyze Option B

The line is increasing, meaning the amount consumed is changing (increasing) over time. This fits.

Step3: Analyze Option C

The graph has a positive slope, so amount is increasing, not nothing. So C is incorrect.

Step4: Analyze Option D

A constant amount would be a horizontal line, but this is a sloped line (increasing), so D is incorrect.

Answer:

B. A changing amount is eaten.
