ROUND WORMS FLAT WORMS

ROUND WORMS EVOLVED AFTER THE CAMBRIAN EXPLOSION. THEY EVOLVED INTO SEGMENTED WORMS. ROUND WORMS ARE VERY CLOSELY RELATED TO FLATWORMS WHICH EVOLVED THE SAME TIME AROUND ROUND WORMS DID.

Where do Roundworms live?

Roundworms started off living in oceans, but as they evolved more, they started to spread out in many places. There are many different roundworms around the world. Places may include in the ocean, on land, or even inside living things. They are sometimes preferred as parasites.

COMMON ROUNDWORMS

Roundworms are the most parasites found in people infected with parasite diseases. They are in the human or animal skin for blood. They usually enjoy moist, warm

areas where an infection can thrive. Free-living roundworms recycle decaying rotting organic matter in almost all environments.

Decomposing and Consuming

Roundworms could be either decomposers or consumers. Without roundworms, organic matter would not be decomposed and the energy supply to plants and animals would be reduced. Roundworms allows minerals and nutrients vital to plants and other organisms to be recycled from bacteria, fungi and decaying organic matter and returned to the soil.

RINGWORMSRingworms are the typical organism in the roundworm family. This is a fungal infection. They usually occur in raw meat from an animal or poor hygiene practices. This picture illustrates a face greatly affected by this organism.

ADAPTATIONS

The roundworms have adapted to almost every environment. They can be found living on, in or around nearly every living organism in virtually every habitat. They also are able to go into a state of cellular hibernation when their habitat is less desirable. They also can adapt deep in the soil on the ground. They feed on many plants.
