If food sources begin to run out , hyphae respond by making spores. why?
Spores production attracts animals, which can be used to transport the fungi to an area where more food available
Fungi changes feeding mechanism once food can no longer be absorbed and the spores production is a by product of this change
Spore production is favoured by natural selection when hyphae are under nutritional stress
Spore production allows fungi to harvest food particle that are floating in air
