Question

a food web is shown in the picture above. which of the following would most likely happen if there was a drought and the grass did not get enough water?
a. the grass would die, which would cause the number of foxes to go up.
b. the rabbits would start eating the foxes, which would cause the number of foxes to go down.
c. the number of rabbits would go up, which would cause the number of mice to go down.
d. the grass would die, which would cause the number of mice, rabbits, and foxes to go down.

Explanation:

Un sequía que mata la hierba (planta) elimina la fuente de alimento única de los conejos y ratones. Sin alimento, sus poblaciones disminuirán, y a su vez, los zorros (que se alimentan de ellos) también verán reducida su población por falta de presas. Las otras opciones no son coherentes con la dinámica de la red trófica: los zorros no aumentarán sin alimento, los conejos no se alimentan de zorros, y la población de conejos no aumentaría sin hierba.

Answer:

D. The grass would die, which would cause the number of mice, rabbits, and foxes to go down.
