Question 1

Nitrogen fixation

Answer 1

Nitrogen fixation is the biological process of converting atmospheric nitrogen (N2) into ammonia (NH3) or ammonium

Question 2

Nitrification

Answer 2

a biological process where bacteria convert ammonia (NH3) or ammonium (NH4+) into nitrite (NO2-) and then into nitrate (NO3-)

Question 3

Denitrification

Answer 3

This process effectively removes nitrogen from the ecosystem and releases it back into the atmosphere, completing a part of the nitrogen cycle

Question 4

inputs and outputs of photosynthesis

Answer 4

sunlight+CO2+H2O —> Glucose +O2

Question 5

inputs and outputs of cellular respiration

Answer 5

Glucose +O2 —> Energy + H2O + CO2
