Answer 1

Saprotrophic nutrition /sæprəˈtrɒfɪk, -proʊ-/ or lysotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed organic matter. It occurs in saprotrophs and heterotrophs, and is most often associated with fungi (for example Mucor) and soil bacteria.
Parasitic nutrition is a mode of heterotrophic nutrition where aparasitic organism lives on the body surface or inside the body of another type of organism (a host) and getsnutrition directly from the body of the host . Helminths: worm parasites. Schistosomiasis is caused by a helminth. 
Holozoic nutrition (Greek: holo-whole ; zoikos-of animals) is a type of heterotrophic nutrition that is characterized by the internalization (ingestion) and internal processing of gaseous, liquis or solid food particles.Protozoa, such as amoebas, and most of the free living animals,such as animals, exhibit this type of nutrition.
