World of Nature Nematodes How they live and affect crops
Nematodes are tiny round or threadlike worms in soil and water. They include Guinea worm and Ascaris and can be parasitic, free living, or predatory. Reproduction varies as eggs hatch, live young, or eggs retained in the mother. They move by a distinctive undulating motion and rely on soil conditions for survival. Plant parasites attack crops like potatoes and tomatoes, causing widespread damage.
