Question 10 (c) 

An animal foraging in a food patch has a net energy gain of by the time it has been foraging for min (where is nonnegative and ). (c) Shown below are functions and representing the net energy gained from foraging in two different food patches for time min. What might account for the decline in in Patch 1? (Write one sentence.) 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you?

Please rate my easiness! It's quick and helps everyone guide their studies. In the graph for we see that the function reaches a maximum net energy gain. A possibility is that the the entire food patch has already been foraged, thus the availability of the food starts declining. Answer:
