Interspecific Competition: Competition within different species
Relationships with Humans: Flatworms have a very helpful relationship with Humans. Marine Platyhelminths are part of healthy streams, ponds, and lakes. They need clean water with lots of oxygen, so when we don't find them, that tells us the water is not healthy, and that we should drink, swim, or use it in any sort of way.
Relationships with other animals/species: These flatworms provide food for animals, such as dragonflies, when they are young. Dragonflies later help us control pests (like mosquitoes) when they are adults.
