Food spoilage microorganisms all need these things, but the specifics may be different
* Food * Water * Proper Temperature * pH * Oxygen
Not all spoilage organisms prefer the same conditions.
Thermophiles like it hot. Psychrophiles like it cold. Most pathogens are Mesophiles - they like what we like.
Yeasts and molds will grow under acid conditions.
Clostridia will form toxins only under anaerobic conditions. Some bacteria can grow both with or without air.

What are the growth requirements for microorganisms?
They need food. But don't feed them after midnight.
What are 3 living things need to be able to live?

How do microorganisms aid in the decay in an ecosystem?
thats because they need food so they feed on dead animals...
How does sugar preserve food?
Sugar preserves food by lowering the water activity (aw). If the aw is 85 or less, spoilage and pathogenic microorganisms can't grow. Microorganisms all need proper food, water, temperature and acidity to grow and adding sugar to appropriate levels can prevent bacterial growth.
How do microorganisms release energy from food such as cheese?
Like all living things,microorganisms need energy and nutrients,which they obtain from food.To release energy from food,carry out respiration.In the process,they give out Carbon dioxide. Can any1 plz give me a better answer than this?Thats all given in my book! :(

Spoilage and pathogenic microorganisms need moisture to grow. When you remove the moisture to below the level that they need, the food will last longer.
How does salt keep food fresh?
Salt absorb water and as a consequence all microorganisms (they need water) are killed.

Why everything need to be covered?
When food is left un-covered, a few things can happen. First off, the temperature might go off (get colder or warm up). This can cause food to spoil quickly. Also, when exposed to air and the outside world, food can become contaminated and full of bacteria.
What substance can microorganisms grow on?
Microorganisms will grow on almost anything organic. Microorganisms need 6 thing to live and reproduce. remember them with the acronym FATTOM Food, the right Acidity, Time, Temperature (40-135 degrees Fahrenheit), Oxygen, and Moisture
Is microorganisms in your bathwater?
yes, microorganisms are small living creatures which we need to have micro-scopes and then we have to enlarge it 300 times to see the small living creatures there is micro-organism in water and food(yeast)

Why is there a need for microorganisms to move?
Because they need to eat too, be it food particles, nutrients or other organisms. Even if they only photosynthesize, they have to move towards the light!
