Question
please explain the right answer and why the wrong ones are wrong.
Suppose you are studying the behaviors of a prey (a small lizard species) and its predator (a large lizard species). The prey uses refuges under rocks to hide when the predator attacks. After an unsuccessful attack, the predator sometimes waits for the prey to re-emerge from the refuge so the predator has another chance. When the prey is a pregnant female, the predator never waits for her to re-emerge, while when the prey is a male, the predator always waits. Which one of the following is a likely explanation of this?
A. Killing a pregnant female decreases the predator's future food source; therefore, it is better in the long run for the predator to kill males.
B. Pregnant females will probably stay in the refuge for longer than males, because they don't have to defend a territory like males do; therefore, it is more profitable for the predator to leave and look for prey elsewhere than to wait for a pregnant female to come out.
C. Because they are 50% larger, pregnant females take 50% longer to be consumed by the predator than male prey; therefore, pregnant females are less profitable to predators, and predators won't wait around for them.
D. Because males are smaller than pregnant females, males can also be killed and eaten by a medium-sized lizard species that competes with the large lizard predator; therefore, to outcompete the medium-sized lizard, the large lizard waits to kill the males of the prey species.
Explanation / Answer
its right answer is B. Pregnant females will probably stay in the refuge for longer than males, because they don't have to defend a territory like males do; therefore, it is more profitable for the predator to leave and look for prey elsewhere than to wait for a pregnant female to come out.
predator dont have well developed nervous system so they can not think about technically views like option no A and C.
