Question

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:

In the graph, the amount consumed each trial remains at 4 throughout the time period. A horizontal line in a graph of amount vs. time indicates no change in the amount over time. Since the amount does not increase or decrease, it means nothing is being consumed (as there is no change from the initial amount of 4). Options like "A negative amount is eaten" would show a downward - sloping line, "A changing amount is eaten" would show a non - horizontal line (either increasing or decreasing), and "A constant amount is eaten" would imply a non - zero slope if the amount was being added or subtracted at a constant rate. Here, the lack of slope (horizontal line) means no consumption (as the amount stays the same).

Answer:

Nothing is consumed.
