Answer:
An oak tree produces thousands of acorns, but very few grow into mature oak trees. The oak exhibits a type 3 survivorship curve.
Type 3 survivorship curve refers to a high mortality rate at an early stage of life. So, acorns are considered to be an oak's "babies," and they don't develop or even survive long enough to become mature adults in the form of oak trees. This is why oaks belong to this type of survivorship curve - the other types do not have such a high mortality rate.
