Unit 3 NitrogenCycle

BMMS Unit 3 Nitrogen Cycle

QuestionAnswer
Nitrogen Cycle Components Atmosphere Nitrogen Gas Lightning Nitric Acid Roots Nitrogen-fixing bacteria Soil Nitrogen Decomposing Consumption by Animals Consumption by Plants
Nitrogen Cycle 1 This element is necessary to make proteins which are needed for many of the process and material of life
Nitrogen Cycle 2 The ______ cycle allows this element to change forms and be utilized by organisms found on planet Earth
Nitrogen Cycle 3 Most of this element (78%)is found on Earth is contained in the atmosphere, however, bacteria in the soil is vital in allowing nitrogen to be usable for other organisms, including plants and animals
Nitrogen Cycle- Atmosphere Nitrogen Gas 78% of the nitrogen found on Earth is in the atmosphere
Nitrogen Cycle- Lightning Nitric Acid Lightning is one mechanism that can change nitrogen into a usable form
Nitrogen Cycle- Roots Nitrogen-fixing bacteria Bacteria found on roots of legumes can fix nitrogen into a usable form
Nitrogen Cycle- Soil Other bacteria can convert fixed nitrogen into nitrates and nitrites for plants
Nitrogen Cycle- Nitrogen Decomposing When animals decompose, nitrogen is put back in the soil
Nitrogen Cycle- Consumption by Animals Animals eat plants that contain nitrogen
Nitrogen Cycle- Consumption by Plants Plants get usable nitrogen from bacteria in the soil
