The six conditions in which pathogens need to grow are as follows: FAT TOM
Food: to grow pathogens need an energy source. Carbohydrates, such as baked potatoes, and proteins, such as beef are some examples.
Acidity: Pathogens grow best in food that contains little or no acid. An example of food with a lot of acid is lemons. Food items with little acid include chicken and cooked corn.
Temperature: Pathogens grow well in food that as a temperature between 41 degrees Fahrenheit and 135 degrees Fahrenheit. This range is known as the temperature danger zone.
Time: Pathogens need time to grow. When food is in the temperature danger zone, pathogens grow. After four hours, they will grow to levels high enough to make someone sick.
Oxygen: Some pathogens need oxygen to grow. Others grow when oxygen isn't there. For example, some pathogens that grow without oxygen would grow quickly in cooked rice.
Moisture: Pathogens need moisture in food to grow. For example, tomatoes and melons have a large amount of water in them, which means they can easily support the growth of pathogens.

∙ 10y agoThis is a far too complicated question to be answered on this site as it is different for each parasite, different for each stage in the life of a given parasite, and for those parasites that have different hosts that they must move between between to complete their lifecycle different in each host.
I suggest the book Parasite Rex by Carl Zimmer as an introduction, but a complete understanding of the subject takes many years of Graduate Degree studies in the field.

Do parasites need oxygen?
yes
What is the difference between biotrophs and necrotrophs?
both are parasites; biotrophs need to keep the organism alive in order to survive, whereas necrotrophs cause necrosis (Tissue death) as they grow through the host.
What is one thing that humans need in order to grow?
The one thing humans need in order to grow is water.
Why plants need soil to grow.?
Plants need soil to grow otherwise they couldn't absorb the water and they would die.
Opening and closing of mouth and gill-slits in fish?
I hav same prob I suspect parasites but not completely sure. I need expert to answer
Can parasites grow in food?
Yes, parasites can grow in food.
Can parasites and virus grow in food?
no. . . Because parasites and viruses can only grow on living matters... There may be saprophytes and bacteria growing in your food. . . Even parasites and viruses can be there but can not grow. .
Organisms that grow on or in other organisms are called?
Parasites.
What types of plants grow without soil?
Parasites. Plants such as Mistletoe ( Viscum album) grow on other plants.
Are greenbrier plants parasites?
Yes The way they grow makes them one
How does sun drying preserve food?
The drying removes the moisture. Microbes need moisture to grow. but some parasites can live on it as you need to put it in the open, so you need to heat it to a high temperature or freeze it before eating
Do parasites need oxygen?
yes
Food that allow microorganisms to grow are called parasites true or false?
True
How do parasites serve as density-dependent limiting factors?
Parasites can limit the growth of a population. They take nourishment from their hosts, often weakening them and causing disease or death. As the population of parasites grow, the population of their hosts tend to decrease.
