Step 2: Gather evidence to construct your explanation. Research ways in which cells get energy.

Use these guided questions to conduct your research:
How do cells in plants (i. e., trees, flowers, etc.) get energy?

How do cells in animals (i. e., birds, horses, humans, etc.) get energy?

What is an obligate anaerobe? How do obligate anaerobes, like the bacteria C. botulinum, get energy?

How does each type of organism get the energy it needs for its essential life processes?
How do organisms get the nutrients they need to survive?
How do nutrients move through an environment? What drives the movement of nutrients?
