BOne year of secondary growth (spring + autumn wood)
COne month of growth in the season
DJust the time when the tree shed its bark
Answer & Solution
Correct answer: B. One year of secondary growth (spring + autumn wood)
One annual ring = spring wood (early year, lighter, wider vessels) + autumn wood (late year, darker, narrower) of ONE GROWING SEASON = ONE YEAR.
Counting rings gives the tree's age.
Dendrochronology studies climate via rings.
