Free-living worms are found mainly in freshwater habitats. Some live in soil. They generally feed on bacteria, fungi, protozoans, or decaying organic matter. By breaking down organic matter, they play an important role in the carbon cycle. 5 мар. 2021 г.
Why are roundworms important and beneficial?
Many species of nematodes are 'free-living', living in soil, sea and freshwater. These feed on bacteria, fungi, protozoans and even other nematodes, and play a very important role in nutrient cycling and release of nutrients for plant growth. Other nematodes attack insects, and help to control insect pests.
Why are roundworms important to humans?
The roundworm has for example been used to study the nervous system and the first cell divisions of the fertilised egg cell. Sulfated glycosaminoglycans, extended carbohydrate chains decorated with negatively charged sulfate groups, have important functions both during early embryonic development and in adults.
What impact do roundworms have?
In most cases, these “wandering worms” cause no symptoms or obvious damage. However, in some cases they can cause damage to tissue. Sometimes they affect the nerves or even make their way to the eyes. In some cases, they may cause permanent nerve or eye damage, even blindness.
What are two important roles of free living roundworms?
Free living nematodes play an important role in soil health, nutrient recycling and adding to the biodiversity of the environments in which they inhabit (Neher, 2010).
