Metamerism also known as segmentation it is the condition in which an organism is made up of linear segments which are similar to each other and may even contain similar organs and tissues. In such organisms the organs and tissues are repeated at regular interval.
Example: Annelidas like tapeworm.

but there is a difference in these two concepts. and the important point is that tapeworm does not belong to annelid phylum. even though it ends with word worm
earthworm belongs to the annelid phylum
It would be earthworms and polychaete but both the concepts are same.
In animals, metamerism is defined as a mesodermal event resulting in serial repetition of unit subdivisions of ectoderm and mesoderm products. Endoderm is not involved in metamerism. Segmentation is not the same concept as metamerism. Segmentation can be confined only to ectodermally derived tissue, e.g., in the Cestoda tapeworms. Metamerism is far more important biologically since it results in metameres, also called somites, that play a critical role in advanced locomotion.
this is the difference between metamerism and segmentation
If this is not copied then Hats off to you
Thanks . my teacher told me this
But if u knew it then why u asked
yes. I wanted to know more about it that's why I type a question

Segmentation, also called metamerism, or metameric segmentation, in zoology, the condition of being constructed of a linear series of repeating parts, each being a metamere (body segment, or somite) and each being formed in sequence in the embryo, from anterior to posterior.
