Question

suppose a bird with a long beak is able to feed on cacti with shorter spines. how will the population of cacti change if this behavior continues? a. the cacti population will increase in number to compensate for the losses. b. the long spined cacti population will become larger than the short spined cacti. c. the cacti population will remain constant in future generations, regardless of spine length. d. the short spined cacti population will become larger than the long spined cacti.

Explanation:

The bird preys on cacti with shorter spines. Through natural selection, cacti with longer spines have a survival - advantage as they are less likely to be eaten. Over time, the long - spined cacti population will grow relative to the short - spined cacti population.

Answer:

B. The long spined cacti population will become larger than the short spined cacti.
