How does nitrogen become part of the food chain?

• Through transpiration by plants

• Through uptake of nitrogen compounds in the soil by plants

• Through factory emission and combustion of fossil fuels

How do  animals get nitrogen?

• the atmosphere 

• eating other organisms

• bacteria

• lightning 

What do the water, carbon, oxygen, nitrogen, a phosphorus cycles have in common?

• All involve liquid substances falling to the Earth from the atmosphere?

• None of the processes works at low temperature.

• All involve the constant cycling of substances between animals, plants, and the Earth.

• All involve the transfer of substances between the earth and outer space.
