Trophic Levels By: Ms. Avery 8th grade Science
Trophic Levels • STARTS WITH THE SUN! Energy = 100% • 1st level (bottom) – Producers CONSUMERS WITH THE MOST ENERGY • 2nd level- Primary Consumers (herbivores or omnivores) • 3rd level- Secondary Consumers (omnivores or carnivores) • 4th level- Tertiary Consumers (omnivores or carnivores) • LEAST ENERGY IN BOTTOM LEVELS!
Trophic Levels Example • Make your own example of a Trophic Level Food Pyramid. Make sure you label what type of consumer they are (ex. producer, herbivore, omnivore, or carnivore) • Also draw an arrow or label how the energy changes from level to level (ex. It decreases)
