Question

How does a distribution curve of body links support a population of fish change after a predator preys on both extremes of body length short and long
The curve separates with a dip in the middle
The curve Shifts to the right
The curve becomes narrower and taller
The curve shifts to the left

Answer 1

The curve becomes narrower and taller.

When a predator preys on both extremes of body length (short and long), it leaves more individuals with intermediate body lengths in the population. This results in a decrease in the number of individuals at the extremes and an increase in the number of individuals in the middle range of body lengths. As a result, the distribution curve becomes narrower and taller, reflecting the concentration of individuals in the middle range of body lengths.
