Morphology
The meaning 'a ring of wood produced each year' is directly derivable from combining 'annual' (yearly) with 'ring' (a circular formation), so a B1 learner who knows both words can infer the concept of a yearly growth ring. This composition follows transparent English compounding patterns and is cross-linguistically common, making the MWE immediately comprehensible.
Etymology
Annual ring comes from the simple image of a tree making one annual ring of wood inside its trunk each year; some rings are thin in dry years and some are wide in good years. So, by counting and looking at these rings people can tell a tree's 'age' and what the year was like.
