They get all their life needs by leeching the very life and energy out of any living thing it can infect, which is called a host. Anything the host eats, the parasites eats. When it wants a snack, it drinks some of the host's blood.

Based on the criteria under questioning the parasites can be classified in several ways - there are ecto- and endo- parasites to start with based on their location on/in the host. Then we have facultative and obligate parasities; while the former can survive in the absence of their host, the later can only survive if the host is present eg., all viruses. Further parasites can be classified based on their taxa - they may be bacteria, virus, fungi, protozoans etc... Parasites can be classified based on what they feed like sanguivorous which feed on blood eg., leeches (can also be classified as ectoparasite and facultative parasite).

They have no parasites
Flies are not parasites.
You can get parasites from sex with an infected person.
They are know as parasites
A parasitic animal is one that lives on or inside of another animal in order to survive. These parasites eat food from the animal they are living in as well as sleek shelter.
They depend on other living organisms to live.
Parasites and predators are alike in the fact that they both depend on another living thing to survive. A predator kills its prey for nourishment while parasites drain their host slowly.

Usually no, they cant survive the acid in our stomachs. The few parasites that can survive the acidity are usually found in uncooked meats and fish.
A hookworm and a tapeworm are classified as parasites because they need a host to survive(get nutrients and energy)
Lice need to feed off of human skin to survive, because they are parasites and can only survive off of another being. It is a common misconception that they can survive alone. Without a site of human skin to feed off of, lice will only survive for 48 hrs and then they will die.
These are parasites and must live on dead matter to survive. They are important because they help to break down this matter and recycle it.
spiders make webs to catch there prey and ticks are parasites the feed off there host.
A parasitologist is a person who studies parasites. They may study how they survive, how they interact with their host, what diseases they may transmit, etc...
viruses are considered parasites (obligate parasites) because they cannot exist on their own. they need the host cell's machinery to reproduce so they cannot "survive" (technically not living) outside the cell.
