After three years of heavy rain, a field of soybeans shows a decreased yield. they have weaker root systems compared to plants in fields where water has been regulated. a fungal pathogen is also found growing in the soggy fields. what hypothesis best explains this phenomenon?

It can be hypothesized that fungal pathogen is responsible for decreased yield.

Explanation:

As the extensive heavy rain changed the climate of that area the soybean plant was effected by pathogenic fungus grown in the field. As we know that fungi makes spores that can withstand harsh environment. Humid and moist environment is favorable for fungi growth. So when spores find a suitable environment they grow rapidly. In the given example, the fungi was pathogenic that produced toxic compounds and effected the growth of soybean plant by damaging its root system and water supply to plant.

answer; i believe the correct answer is (sporophyte);
