So i got fried tdy nd didn't finish my biology homework so I was wondering if anyone can answer these two questions for me:
1. Some fungi are considered predatory—they can capture and kill nematodes and other tiny soil organisms. Conduct research to determine how they do this. How is this activity related to the availability of nitrogen?

2. In the absence of oxygen, yeast ferment sugar to obtain energy. This process releases carbon dioxide gas and ethanol (an alcohol). How do humans take advantage of this process in the manufacturing of foods and beverages?

Im begging somone pls help my dumb ass
