1. Investigation 1 Claims:
Essential Question: How do carnivorous plants get energy and matter within an ecosystem? Investigation Question: How does energy cycle within an ecosystem?
Investigation 1 Claims:
The main source of energy in an ecosystem is the food. The molecules in food give organisms energy to live. As organisms eat other organisms, energy is maintained throughout the ecosystem.
Terms of Use:
Carbon, Hydrogen, Oxygen, Nitrogen, Carbohydrates, Protein, Fat/Lipids, Calories, Macromolecules, Nutrients, Chemical Bonds, Producers, Consumers, Decomposers, Trophic Levels, Food Chain/Web

2. How does energy cycle within an ecosystem?
Evidence 1.1
Justification
How does the evidence justify the claim that the main source of energy in an ecosystem is the food?
Terms: Nutrients, Producers, Consumers, Decomposers, Trophic Levels

3. How does energy cycle within an ecosystem?
Evidence 1.2
Justification
How does the evidence
justifies the claim that
the molecules in food
give organisms energy
to live?
Terms: Carbon,
Hydrogen, Oxygen, Nitrogen,
Carbohydrates, Protein,
Fat/Lipids, Calories,
Macromolecules, Nutrients,

4. How does energy cycle within an ecosystem?
Evidence 1.3
Justification
How does the evidence
justify the claim that as
organisms eat other
organisms, energy is
maintained throughout
the ecosystem?
Terms: Producers,
Consumers, Decomposers,
Trophic Levels, Food Chain/Web

5. Investigation Question: How does energy cycle within an ecosystem?
Claim: The main source of energy in an ecosystem is the food. The molecules in food give organisms energy to live. As organisms eat other organisms, energy is maintained throughout the ecosystem. Justification: The claim is supported by evidence because… Evidence: Use the evidence presented (1.1 – 1.3) to justify the claim stated above.
