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.

A clams growth rings can be, tan, gold, brown, even red.
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.
Most of a tree's trunk is not made of growth rings, but these rings are an important part of its structure. Growth rings, formed by annual layers of new wood, represent the tree's growth over time and can be seen when a trunk is cross-sectioned. The trunk itself is primarily composed of various types of wood, including sapwood and heartwood, which provide strength and support. The growth rings help indicate the tree's age and growth conditions but are just a part of the trunk's overall composition.
the size of the rings would depend on the growth cycle of the tree. If the growth time for a certain year is longer, the ring will be wider, it the growth time of the year is shorter then the ring will be smaller.
