Trophic Level Notes. Energy Flows. Energy flows through an ecosystem as one organism eats another Group organisms based on how they obtain energy (producer vs. consumer) Trophic level is where they are in the sequence of energy transfers. Why is energy transfer so low?

Energy Flows • Energy flows through an ecosystem as one organism eats another • Group organisms based on how they obtain energy (producer vs. consumer) • Trophic level is where they are in the sequence of energy transfers
Why is energy transfer so low? • Some organisms escape being eaten • Some molecules can’t be broken down by predators • Example a mountain lion won’t eat antlers, hooves or hair • Some energy lost as heat
Higher trophic levels contain less energy and can support fewer individuals
