Dear student
Aspergilli can be found throughout nature with their spores being abundant in air .
In addition to largely being saprophytes that obtain their nutrition from dead and decaying matter
they can also be pathogenic to human beings and animals with some also affecting and damaging plants. Because they lack chlorophyll ,and are therefore unable to produce their own food. they are dependent on other material in their surrounding for nutrition . here is worth nothing that Aspergilli are incapable of absorbing organic matter in their surroundings
