Fungi survive in unfavorable conditions by parasitism.Parasitism means an ability of an animal to obtain nutrients from other animals by using them as hosts.
Also Fungi have the ability to survive in climatic extremes and in long periods of drought, because they have been specially designed to be resilient.
Microorganisms do survive in unfavorable conditions by producing spores. Spores are the reproductive structures that is adapted for surviving for extended periods of time in unfavorable conditions. They also enter into stationary phase during which they require less nutrients, and use the ones they have at a much slower rate.
How do microorganisms protect themselves under unfavourable
conditions
By forming endospores.
forming endospheres
Advantages - Spores are covered by a hard protective coat which enables them to survive under unfavourable conditions like lack of water and extreme temperatures. But when the conditions are favourable, the spores grow to produce new plants. This help them to run their species at any type adverse condition or environment. Thus the advantage is that despite of unfavourable environment, their species will not be demolished.Disadvantages - spore formation process is quite primitive.
endospores
Spores are like the seeds in flowering trees and conifers except they are smaller and many thousand can be released in one spore sac. The spores enable a plant to grow again but only ferns, mosses and liverworts have spores.
It allows the bacteria to create a resistant and dormant cell that can preserve the original cells genetic material when put under extremely unfavourable conditions
Spores are formed when cells are under unfavourable conditions, as for the bacteria they are means of survival. So the older the culture the higher the cell number in that culture, which means less nutrients for the cells. Under this conditions cells will start spore production. Depending on the "age" of the culture you can get a mixture of vegetative cells with spores inside and spores that are already released or mostly spores with rare vegetative cells, which means the cells are dead.

micro organisms form spores called as endospores which protect them from all unfavourable condition
endospores
Bacteria can form capsules and spores. A capsule is a protective layer around some bacteria. They can be virulent as they can resist the body's defence mechanism. Bacteria can change into bacterial spores when the environmental conditions are unfavourable. In this condition bacteria are inactive. When the environmental conditions become more suitable the bacteria can become active and cause disease. Bacterial spores are extremely resistant and can survive most forms of disinfection and inadequate sterilisation

Not all of the spores survive.
Formation of bulbous stem to overcome unfavourable conditions of growth.
Bacteria's reproduction can be slowed down by changing their favourable conditions into unfavourable conditions required for their reproduction.
When harsh conditions exist, the spores will enter dormancy, and will only resume activity or growth when favorable conditions exist.
