a. parasitic nutrition
b. symbiosis
c. saprotrophic nutrition
Answers
Explanation:
a) saprophytic nutrition= organisms dervi their food from dead and decaying materials are called parasitic nutrition.
fungi... etc
parasitic nutrition= parasites live inside or outside plants and derive nutrition from it.
ex , leaches , amerbell, tapeworm etc
symbiosis =Symbiosis is any type of a close and long-term biological interaction between two different biological organisms, be it mutualistic, commensalistic, or parasitic.
Explanation:-
Parasitic nutrition is where an organism lives in or on its host and acquires nutrition at the expense of its host. Examples include lice and tapeworms.
Symbiosis is the phenomenon by which two organisms maintain relationship with each other to be mutually benefitted. Organisms involved in this type of relationship are called as symbionts. e.g. Rhizobium bacteria and Leguminous plants are symbionts exhibiting symbiosis.
The mode of nutrition in which an organism obtains nutrients from dead and decaying organic matter is called saprophytic nutrition. Example - Rhizopus (bread mould), Mucor (pin mould), Yeast, Agaricus (mushroom)
