In the energy pyramid here, which organisms have the most energy available?

• Producers
• Carnivores
• Herbivores
• Top Predator

In the energy pyramid above, which organism has the least amount of energy available?

• Producers
• Herbivores

What decreases as it we move up the pyramid?

• Aggression of the organisms
• Pollution/Toxins
• Available Energy
• The distance above the ground they live

The amount of energy decreases as you move through a food chain because

• There are less consumers
• The amount of sunlight decreases
• Most of the energy (90%) is lost or used in life processes
• Non-sense, energy increases!

The plants were sprayed with a toxin. Which level would have the highest concentration of toxins as it travels through the food chain?

• The Snake
• The Mice
• The Plants
• It would be equal everywhere

In the energy pyramid here, how much of the energy in the producers gets passed to the herbivores?

• 10%
• 20%
• 80%
• 90%
