Nematodes are wormlike organisms which can be seen with naked eye, live in water-filled pore spaces in the soil. Nematodes are in large number in the upper soil layers where organic matter, plant roots, and other resources are most abundant.
The functions of nematodes:
- Free-living nematodes decompose organic material into nutrients and cycled them in the soil by feeding on some bacteria and fungi.
- Nematodes help in distributing bacteria and fungi through the soil and along roots by carrying live and dormant microbes.
- They used as food for higher predators, soil microorthropodes.
- They eat disease-causing organisms, thus suppress their growth.
- They acts as potential bio- control agents.

selective breeding has changed organisms over time by paring that organism up with another organism of its kind with desirable traits. take dogs for example, through selective breeding we now have many different types of dogs with different abilities. i hope this helps
