Growth rings develop in trees, one each year. They are the result of there being less available water during one part of the year, so the water carrying vessels (xylem) are smaller than during the other half of the year. You can calculate the age of a tree that has been cut down by counting how many rings the wood has.
Yes, growth rings have been found on fossilized fish scales. These rings, similar to tree rings, can provide information about the age and growth rate of the fish during its lifetime. Studying these growth rings can help researchers understand the fish's environment and lifecycle.
No, growth rings are not typically found on living clam shells. They are commonly found on fossil clam shells and can provide information about the age and growth patterns of the clam when it was alive.
Do your homework and you would know.
Tree growth rings are concentric circles found in the cross-section of a tree trunk. Each ring represents one year of growth, with the width and characteristics of the rings providing information about the tree's age, environmental conditions during each year, and the tree's overall health and growth patterns.
Annual growth rings are commonly studied in trees.

No, trees are not the only organisms with growth rings. Some shrubs, palms, and certain types of woody plants also exhibit growth rings, which can indicate age and growth conditions. Additionally, some species of fish, corals, and mollusks can display growth rings in their skeletal structures. These growth rings provide valuable insights into the growth patterns and environmental conditions experienced by these organisms.
A clams growth rings can be, tan, gold, brown, even red.
Brachiosaurus, a genus of large dinosaurs, did not have rings in the sense of tree rings or similar structures. However, if you are referring to the rings found in some plants, those are typically growth rings that indicate the age of a tree. Brachiosaurus lived during the Late Jurassic period and primarily fed on vegetation, but its anatomy does not feature any rings.
Palms do not show growth rings.
The rings on a clam show where the growth of one year ends. Basically you can count the rings to see how old the clam is just like a tree! Each ring shows the growth of that year.
Tree growth rings (and some other kinds like those of shells) are caused by the difference in growth during the different seasons: autumn and winter less growth, spring & summer more growth.
