Perhaps one of the basic aspects of life is the conversion of energy from one form to another.
To grow and reproduce typically means adding mass & matter, thus an organism would need to increase it's matter through nutrients as well as replacing what was lost when dividing.
Plants and algae can make hydrocarbons out of water and carbon dioxide (two vital nutrients for them), but they also require other minerals including phosphorous & Nitrogen in various forms.
Bacteria, Protozoa, and other microorganisms that are unable to photosynthesize require energy from their nutrients, as well as using the nutrients as the basic building blocks to grow and divide.
microorganisms cause diseases and give people virus.
Every organism needs a source of energy but some bacteria can utilize the sun for energy as well as minerals in the soil for an electron donor and make their own food.
They multiply by splitting into several thousand equally sized pieces, then get in a Van and pop to asda.
Some micro-organisms make their own food; some absorb nutrients from organisms that they live in or on and some absorb nutrients from wastes or dead matter.
yes
Why is it that dried food sample can contain lower numbers of microorganisms
Microorganisms are used in food such as cheese and yogurt.
changing atmospheric nitrogen to a usable form
Photosynthetic microorganisms are organisms that are microscopic or cannot be seen with an eye and they can preform photosynthesis. Photosynthesis is when an organism uses; water, carbon dioxide, light energy to make food for itself.
They digest food with enzymes; breaking down large molecules into small ones.
Four factors which affect the growth of microorganisms are: temperature food source for microorganisms (ie. sugar, protein, fat) the amount of microorganisms introduced to the food source ph of the food source
they reproduce more than food poisoning microorganisms. In food poisoning the microorganisms are spreadable but not in food borne microorganisms :) Hope his helps Janet
Microorganisms help break down and decompose food. These microorganisms are what cause food to spoil and grow mold on it.

no
Phytoplankton are microorganisms that live in the water and can photosynthesize, which are key to the marine food chain since they are at the bottom of the chain. Also, some microorganisms are filter organisms, which get their food by cleaning out junk from the water or air.
Steril processing technicion microorganisms is used for food production.
The beneficial microorganisms introduced into this food give it it's unique flavor would be cheese.
yes because food is also a matter.
Microorganisms can reach your food for several different reasons. Some foods and drinks are made with microorganisms as an ingredient such as the bacteria used to make cheese. Other microorganisms can come from someone handling food without washing their hands or several other sources.
