suter [353]

If the number of blue jays increases, the two likely effects on other populations are both the number of mice and the number of caterpillars will decrease.

  • An organism that preys on other species in order to consume them as food is referred to as a predator.
  • Prey is a term used to describe an organism that a predator kills.
  • An ecosystem's ability to balance an expanding prey population depends on the interaction between predators and their prey.
  • Blue jays and crows both rely on mice and caterpillars as food sources, as indicated by the current circumstance.
  • Mice, caterpillars, and blue jays are the prey, while crows and crows are the predators. The two prey populations will decline if the number of blue jays rises.

Hence, both the number of mice and the number of caterpillars will likely drop as the number of blue jays rises, having two possible implications on other populations.
