2) Lightning and bacteria act to move and convert______from the air into compounds in the soil that can be readily used by plants.

Thank you so much! :D

Answer 1

1. carbon dioxide (CO2)

by means of photosynthesis if you want to look into it more.

Energy + Water + Carbon Dioxide = Glucose + Oxygen

2. nitrogen

Legumes (such as soybeans) specifically have a symbiotic relationship with nitrogen fixing bacteria. That might be important.
