Anything Parasitic has a negative effect on its host. Symbiotic relationships between the parasite and the host means that the effect is not negative but instead both sides benifit from the grouping.
Parasitic roundworms can significantly impact their host organisms by draining nutrients, leading to malnutrition, weakened immune responses, and reduced overall health. In severe cases, they can cause debilitating diseases or even death. Additionally, these parasites can disrupt ecosystems by affecting host populations, potentially leading to imbalances in food webs and biodiversity. Overall, their presence can have far-reaching effects on both individual hosts and larger ecological communities.
The only roundworms that have a symbiotic relationship with humans live in our digestive tracts. They absorb nutrients and release toxic waste without giving us any benefit. Thus, roundworms have a parasitic relationship with humans. Technically parasitism (one organism benefits, the other is harmed) is considered a different form of interaction between species as symbiosis (both organisms benefited). The other possibility is commensalism (one organism benefits, the other is not affected).
many many other organisms. Nematodes (parasitic worms), parasitic flies, single-celled parasitic organisms and many others. See Wikipedia on Parasites.
Ascaris, a genus of parasitic roundworms, do not have eyes. Instead of eyes, they have specialized sensory structures that help them detect changes in their environment. These structures allow them to sense light, chemicals, and other stimuli, which are important for their survival and behavior in their host organisms.
Yes because it obtains its nutrients from other organisms.

Parasitic organisms are those that live at the expense of other organisms. Often, parasites feed on other animals. For example, mosquitos are parasites because they feed on the blood of other living things. Mosquitoes sometimes carry parasitic microorganisms too, like plasmodium falciparum, which is the protozoan that causes malaria.

Ticks latch on to other organisms and feed off them.
Roundworm infections are diseases of the digestive tract and other organ systems caused by nematodes. Nematodes are parasitic worms with long, cylindrical bodies.
