Nematoda Habitat

-Nematodes may be the most common of all multi-cellular animals:

-A single rotting apple may contain ____________________ roundworms!

-An acre of topsoil can contains ____________________ roundworms!

-There are ____________________ species of named nematodes and it is believed there could be as many as ____________________ species in total.

-Nematodes are found free living in soil and aquatic habitats (and act as important decomposers there) and as predators inside many plants and animals (humans included).
