A. Guppies from low-predation ponds reach larger body sizes and produce more nitrogen.
This conclusion is supported by the data presented in the figure, which shows that guppies from low-predation ponds with larger body sizes excrete more nitrogen.
Guppies and Predation:
This bar graph shows the nitrogen excretion rate for guppies as a function of predation. The orange bar indicates nitrogen excretion for guppies from low-predation ponds. Guppies with larger body sizes excrete more nitrogen.
Use the passage to answer the question.
Which of the following conclusions is the best interpretation of the data presented in the figure?
A. Guppies from low-predation ponds reach larger body sizes and produce more nitrogen.
B. Guppies from high-predation ponds produce less nitrogen to avoid being detected.
C. Guppies from low-predation ponds digest food less efficiently, thus producing more nitrogen.
D. Guppies from high-predation ponds reach larger body sizes to avoid being eaten and digest food more efficiently, thus producing less nitrogen.
