1. Investigation 2 Claims:
Essential Question: How do carnivorous plants get energy and matter within an ecosystem? Investigation Question: How does nitrogen cycle within an ecosystem?
Investigation 2 Claims:
Microbes (bacteria) are able to fix nitrogen for plants from the atmosphere. Assimilation of nitrogen by plants allows them to make proteins for growth. Nitrogen is able to return to the atmosphere through fungus and bacteria.
Terms of Use:
Nitrogen Fixation, Denitrification, Nitrifying Plants, Decay, Fungus, Assimilation

2. How does nitrogen cycle within an ecosystem?
Evidence 3.1
Justification
How does the evidence justify the claim that microbes (bacteria) are able to fix nitrogen for plants from the atmosphere?
Terms: Nitrogen Fixation, Nitrifying Plants

3. How does nitrogen cycle within an ecosystem?
Evidence 3.2
Justification
How does the evidence
justifies the claim that
assimilation of nitrogen
by plants allows them to
make proteins for
growth?
Terms: Nitrogen Fixation, Assimilation

4. How does nitrogen cycle within an ecosystem?
Evidence 3.3
Justification
How does the evidence
justify the claim that
nitrogen is able to return
to the atmosphere through
fungus and bacteria?
Terms: Denitrification, Decay, Fungus

5. Investigation Question: How does nitrogen cycle within an ecosystem?
Claim: Microbes (bacteria) are able to fix nitrogen for plants from the atmosphere. Assimilation of nitrogen by plants allows them to make proteins for growth. Nitrogen is able to return to the atmosphere through fungus and bacteria. Justification: The claim is supported by evidence because… Evidence: Use the evidence presented (3.1 – 3.3) to justify the claim stated above.
