You are doing a research project to determine the age of maple trees in a series of 100 square meter plots.Your data are interesting because many of the trees that are the same age are not the same size,even though they are within a few kilometers of one another.Why might this be?

A) Trees are long-lived and unitary organisms. As a result, some individuals may have experience competition and predation that has affected growth and development.
B) Trees of the same age should all grow differently because they are semelparous perennials.
C) Trees are long-lived and modular organisms. As a result, some individuals may have experience competition and predation that has affected growth and development.
D) Trees of the same age should all grow differently because they are iteroparous annuals.
