Answer

Cuscuta, ticks, lice, leeches and tapeworm

Reason — Cuscuta, ticks, lice, leeches and tapeworm have same mode of nutrition since all the organisms in this group exhibit a parasitic mode of nutrition.

In parasitism, an organism (the parasite) lives either on or inside another living organism (the host) and derives nutrients from it, often harming the host in the process.

  • Cuscuta (Amarbel) is a parasitic plant that absorbs nutrients from the host plant using special structures called haustoria.
  • Ticks and lice are external parasites that suck blood or feed on the skin of animals.
  • Leeches are also external parasites that feed on the blood of other organisms.
  • Tapeworms are internal parasites that live inside the intestine of their host and absorb digested food.

Thus, cuscuta, ticks, lice, leeches and tapeworm share the same mode of nutrition — parasitic.
