Step 1: Watch the StudyJams video on the Nitrogen Cycle here. When you are finished watching the video, complete the "Test Yourself" quiz.
Step 2: Read the key points of today's lesson below.
- Nitrogen is important to living things because plants and animals use it to make protein, which allows plants and animals to live and grow.
- Plants and animals cannot use nitrogen in gas form.
- Bacteria in soil "fix" nitrogen gas by turning it in to usable nitrogen compounds.
- Plants absorb the usable compounds in the soil.
- Humans and animals eat plants to get nitrogen.
- When plants and animals die, bacteria and decomposers release nitrogen from their body back into the atmosphere.
Step 4: Check your work at the "Checkpoint" tab above.
Step 5: Create your own nitrogen cycle diagram. Your diagram MUST include:
- A picture of one producer
- A picture of one consumer
- Bacteria
- Steps explaining how nitrogen is cycled in the nitrogen cycle.
