Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.
Answer:
PHOTOSYNTHESIS
carbon dioxide(CO2)+water(H2O)+sun light in the presence of chlorophyll(C55H72O5N4Mg)⇒glucose(C6H12O6)+oxygen(O2)+ATP(energy)
RESPIRATION
Glucose(C6H12O6)+Oxygen(O2)⇒carbon dioxide(CO2)+water(H2O)+oxtgen(O2)

The correct answer is c. human movement that is used to communicate messages between people.
Explanation:
Body posture comes under non-verbal communication. Most of the time people communicate non-verbally than verbally by facial expression, body posture, appearance, and gesture.
Body posture says a lot of things about a person like if a person's body posture is straight that shows that the person is focused, interested and confident but if a person has stooped posture while sitting or standing gives a message that the person is bored and lack self-confidence.
Body posture also affects the health and personality of any individual. Day to day lifestyle of modern life is hugely responsible for people's bad body posture and health issues.
