An experimental forest ecosystem is enclosed in a sealed greenhouse. The entire ecosystem, including the air and soil, is treated with an extremely potent fungicide that kills all fungal life stages including spores. What will probably happen next?

Question

Quizplus · Accepted Answer

The potent fungicide will kill not only harmful fungal pathogens but also beneficial ones, such as mycorrhizae. These fungi are important partners for plant growth and nutrient uptake, so their loss will likely lead to a decline in plant growth due to the lack of nutrients and the accumulation of dead organic matter. This may ultimately cause a change in the entire ecosystem.
