Nematodes can be categorized into three basic groups: free-living nematodes, which primarily inhabit soil and aquatic environments; plant-parasitic nematodes, which feed on plant roots and can cause significant agricultural damage; and animal-parasitic nematodes, which infect a variety of animals, including humans, often leading to health issues. Each group plays distinct ecological roles and has varying impacts on their environments and hosts.

tabs, groups, and commands
There are the food groups dairy, proteins, vegetables, fruits, grains, and oils.
The eight groups are:* Mollusks * Echinoderms * Arthropods * Annelids * Nematodes * Porifera* Platyhelminthes * Coelenterates Or go to:What_are_the_8_groups_of_invertebrates
There is some debate about what other groups the nematodes, or roundworms, are most closely related to, and therefore from what group they descended. Nematodes are classified as being in the clade Ecdysozoa which also includes arthropods. If nematodes are truly closely related to arthropods then they share a common ancestor.

Asteroids are categorized into three basic groups: C-type (carbonaceous), S-type (silicaceous), and M-type (metallic). These groups are based on their composition, with each group having distinct characteristics based on the types of materials they are made of.
The three basic groups in society are lower class, middle class, and upper class. An example of each group would be: lower class - minimum wage workers; middle class - teachers; upper class - CEOs.
The three basic groups of parts in a modern firearm are: the action (which includes the trigger, firing pin, and bolt), the barrel (where the bullet is fired from), and the stock or frame (which provides structure and support for the other parts).
