Energy Pyramids

Why can there not be many carnivores in an ecosystem? 

• Because carnivores are at the top of the pyramid and there is usually not enough energy to support a lot of carnivores at the top.
• Because carnivores are at the top of the pyramid, and there is too much energy left at the top of the energy pyramid
• None of these
• Both of these

If there is 1000 Kcal available in the producers in trophic level 1, how much energy is available in the herbivores in trophic level 2?

• 10 Kcal
• 1 Kcal
• 100 Kcal
• 1000 Kcal

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

• 10%
• 20%
• 80%
• 90%

In the energy pyramid here, how much of the energy in each level gets lost as heat or used by the organism for survival?

• 80%
• 90%
• 10%
• 20%

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

• Producers
• Herbivores
• Carnivores
• Top Predator

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

• Producers
• Carnivores
• Herbivores
• Top Predator

In an energy pyramid, energy_______ as you move up the pyramid.

• Increases
• Descreases
• Stays the same
• Changes up and down

An energy pyramid shows...

• Different organisms of the food chain organized into a pyramid
• The change in the amount of energy available for each type of organism in a food chain
• Both of these
