  "id": "MLC-T-ENV-012738",
  "term": "Growth Ring",
  "field": "Environment",
  "definition": "The layer of wood growth put on a tree during a single growing season. In the temperate zone, the annual growth rings of many species (e.g., oaks and pines) are readily distinguished because of the differences in the cells formed during the early and late parts of the season. In some temperate zone species (e.g., black gum and sweetgum) and many tropical species, annual growth rings are not easily recognized.",
