Solution

The organisms mentioned in your question, such as Cuscuta (a parasitic plant), lice (ectoparasites), leeches (some species are parasites), and tapeworms (intestinal parasites), primarily exhibit parasitic nutrition.

Explanation:

  1. Cuscuta: This plant does not perform photosynthesis like typical plants. Instead, it attaches itself to host plants and derives nutrients directly from them.

  2. Lice: These are small parasites that live on the surface of a host (typically animals or humans) and feed on their blood or skin.

  3. Leeches: While some leech species can be detritivores, many are blood-feeding parasites that rely on other animals for nourishment.

  4. Tapeworms: These are intestinal parasites that live in the intestines of their host organisms, absorbing nutrients through their skin from the host's digested food.

Thus, the common nutritional mode shared by these organisms is parasitic nutrition.
