What is meant by the term "Mode of Nutrition"?

Postby LMJ » Sun Jun 04, 2006 1:24 pm

I'm an A-level Biology student, and I have my Ecology exam coming up this week. I was going through a past paper, and I came across a question that showed a diagram of an organism called Rhizopus, which I gathered was a kind of fungus. The first question said: "What mode of nutrition is carried out by Rhizopus?" I know that fungi are heterotrophic organisms, but would it have been correct to put "heterotrophic nutrition"? I've been searching through my textbooks and every single Biology website, and I can't find one definition for this term... I'm getting rather worried that there's going to be an important question on my real exam about this. I'd be very grateful if anyone could shed some light on this! Thank you!

They're saprophytic, like most other fungi. This means that they absorb decaying or decayed organic material for nutrition and energy. Rhizopus specifically is responsible for many types of mold etc. It's in the Zygomyctes.

Thank you very much! I knew that they fed on dead organisms, but I wasn't sure if there was a specific term for that. The link you provided was very useful, thank you!
