Question

In parasitic mode of nutrition, is the food obtained by diffusion or osmosis? If not then how does this process take place?

Answer 1

Diffusion is the process in which molecules tend to move from an area of high concentration to an area of low concentration.

Osmosis is the diffusion of water molecules through a membrane.

In parasitic nutrition, no diffusion or osmosis of molecules take place.Food is taken directly without such movement of molecules.

In Parasitic nutrition, a parasitic organism lives on the body surface or inside the body of another type of organism (a host) and gets nutrition directly from the body of the host.
