How can organisms that don't use starch grow on a starch agar plate?

There are other nutrients in the media that they can use to grow

It depends; quite often it comes from a water plant called agar.

Bacteria are prokaryotic, meaning 'without nucleus'. The basic bacteria has a cell membrane, which holds in its cytoplasam and genetic material. The bacteria holds lots of ribosomes for creating proteins, which are ever so important in a living organism. Bacteria do not have a cell wall, this is plant cells (eukaryotic) only. Some bacteria have tiny hairs covering the body called silia aiding in movement. Other have a single hair, or maybe two, this is called a flagellum. I typed this fast so spelling may be off, but the information is correct.\n\nthefeistyguy

you can surely rule out some things based on the type of plate you are using.  assuming that you have covered that base, you can separately pick a colony that you think may be a contaminant and look for differences in growth patterns, color, morphology, gram stain, growth on other media, and if all else fails, you can sequence it to find out exactly what it is.

Most of the bacteria that can be cultured represent only a tiny fraction of what's out there. Bacteria exist in practically every niche observable but in general, the best way to cultivate bacteria is to simulate their natural environment. That's why many infectious bacteria are grown on agar (a sugar similar to the ones found in our body) and incubated at 37 degrees celsius (the temperature of the human body)

Maybe prokaryotes. But I'm not sure... I think there's still a debate about them cause they're not really living creatures... They are "alive" when they are inside a host, but otherwise, they're just lifeless proteins.. :)

Physically, their roots help push apart the logs so bacteira can get in. Chemically, they digest the logs and have their own bacteria that grow on them symbiotically.

Certainly not.  There are tons of unicellular organisms like amoeba and other protozoa that are quite nicely alive, but don't have any form of sexual reproduction, so don't come from an egg.

Non-living. It cannot reproduce by itself, cannot regulate homeostasis, depends/hijacks other hosts for reproduction. It's mostly leftover/waste DNA of some bacteria/protist that ejects their DNA into the air with a protein capsule to reproduce, although this didn't work.

I don't know who told you this but it simply isn't true. Microbes certainly will grow in food if there is no oxygen.  \n\n\nIn fact one of the worst food poisoning microbes will ONLY grow if the food conatibns no oxygen.  That microbe is called Clostridium botulinum and is reposnsible for the disease botulism.\n\nTher are also many, many othermicrobs that will live and grow quote happily in food with no oxygen.

They don't...their shells grow with them.  Only hermit crabs get brand new shells.  Everything else either molts or has a shell that grows with the body.

Heterotrophic organisms like us and other animals, like reptiles and mammals, can't make their own food;\nParasites, like tapeworm, cuscuta etc. take it from other 'host' organisms;\nAnd saprophytes, like mushrooms, feed on dead and decaying organisms.\nOnly autotrophes can make their own food, i.e., only green plants and bacteria containing chlorophyll, called autotrophic bacteria.\nHope this answers your question.

I don't have a very specific answer for you, but maybe this will help.  PDA is generally used for growing fungi, and is not an especially good medium for bacteria\n\n"Potato dextrose broth (abbreviated as "PDB") and potato dextrose agar (abbreviated as "PDA") are common microbiological media for culturing both yeast and mold, but usually not bacteria."\nhttp://en.wikipedia.org/wiki/Potato_dextrose_broth\n\n... though I did read this:\n\n"Potato dextrose agar is the most widely used medium for growing fungi and bacteria which attack living plants or decay dead plant matter."\nhttp://www.disknet.com/indiana_biolab/b029.htm\n\nHopefully that will narrow down your search!

ants are the coolest-all over the world different species work in large colonies to do amazing things, they practice agriculture: some cultivate a species of fungus to eat using cut up leaves as substrate and every time there is a new colony to be formed they bring the fungus with them. Some raise aphids like cows protecting them from predators to feed on a sweet secretion they produce. Some live in specialy evolved hollow spaces on plants built specifically to house ants who in return protect the plant from any intruder and even vines that try to grow on it-they will even weed out plants trying to grow on the ground around it! They also wage wars against other ant colonies, and that's just the beginning....

depends on what classes of microbe you are reffering to: aerobic (needs oxygen) or anaerobic (oxygen is poison to them). Most all microbes love molasses and high starch items like rice. These substrates offers a wide spectrum of minerals and sugars. The minerals provide "enzyme bridges" for different kinds of microbes to exist "happily" together (even aerobes and anaerobes).
