plants that convert the nitrogen through the biochemical process of photosynthesis

animals breathing atmospheric nitrogen and converting it into usable forms through respiration

bacteria that convert the unusable nitrogen into useable forms

fungi that are able to grow in dark conditions by utilizing nitrogen as an energy source

Answer 1

nitrogen fixing bacteria

Answer 2

So it´s C?

Answer 3

yup

Answer 4

Nitrogen fixation. Common plants that live symbiotically with atmospheric nitrogen are called legumes and are of great importance in agriculture and the human and animal food chain. There are other forms life of N2 fixation but this one is of the most important. Converting atmospheric N2 to NH3 occurs by certain bacteria (Rhizobia) are living in nodules growing on the roots of the plants.
