1) Bacteria and fungi need certain conditions for their life, such as moisture, the right temperature, and organic matter, while bacteria do not have chloroplasts.
Photosynthesis is not possible.
To make organic matter, you must live on ready-made organic matter Therefore, the first thing to do is to prepare a medium containing nutrients, which can be added with beef juice and agar.
(2) Sterilize the medium and all utensils at high temperature to kill the bacteria and fungi in the medium and petri dish, so as to prevent the interference of miscellaneous bacteria in the experiment, so as not to affect the results of the experiment; (3) After inoculation, the petri dish should be placed in an incubator with a constant temperature (such as 25) or cultivated in a warm place indoors, because this is suitable for the growth of fungi, so the answer is: (1) organic matter (2) high temperature (3) constant.

First of all, it is necessary to prepare a medium containing Qi Ye's nutrients, which can be boiled with beef juice and agar; Then the medium and all utensils are sterilized at high temperature to prevent the interference of miscellaneous bacteria on the experiment; In order to prevent high temperature from killing bacteria and fungi, it is necessary to wait for cooling before inoculation; After inoculation, place in a warm place for constant temperature culture Note: Observe regularly and record the experimental phenomena in detail
So the answer is: high temperature sterilization; Inoculation.
