Oak trees produce seeds that are contained in acorns. Blue jays eat the seeds in acorns. Blue jays also collect acorns and hide them in the ground, often far away from the parent oak tree. Blue jays do not eat the seed of every acorn they hide. How do oak trees benefit from blue jays’ collecting and hiding acorns?  

Blue jays help with the reproduction of oak trees because new oak trees will grow where the acorns are buried.
