Answer:

Metamerism helps in finding and feeding of food particles. These annelids have a well market internal & external segmentation each body segment bearing a pair of appendages on parapodia. Polychaetes with numerous out usually similar segments except for the head and anal segments.metameric segmentation The repetition of organs and tissues at intervals along the body of an animal, thus dividing the body into a linear series of similar parts or segments (metameres). It is most strikingly seen in Annelida.

Explanation:

The repetition of organs and tissues at intervals along the body of an animal, thus dividing the body into a linear series of similar parts or segments (metameres). It is most strikingly seen in Annelida. Essentially, metameric segmentation is an internal, mesodermal phenomenon, the body musculature and coelom being the primary segmental divisions; this internal segmentation imposes a corresponding segmentation on the nerves, blood vessels, and excretory organs. In some metameric animals the segmentation is visible externally but in others (e.g. Chordata) external segmentation has been lost and internal segmentation is best seen in the embryo. Metameric segmentation is thought to have arisen as an adaptation to more efficient locomotion.can i hope a brainlist and thanks

Answer:

In some animal body is internally or externally divided into segment which a serial repitation of at least some organ for example :-earthworm the body show this type of pattern is called metameric segment this is found in Aneelida, Arthopoda, Chordata
