Science 20 Unit A Lesson 1.1-1.3

What is the bottom layer of the an energy pyramid?

• producer

• tertiary consumer

• Secondary consumer

• primary consumer

What does an energy pyramid show?

• Energy flow in a community

• Longest lifespans

• The stronger animal the higher it is on the pyramid

What would happen if their were no producers?

• Every population would grow larger

• Everything would die out

• The animals would make their own food

What would happen if the primary consumers died out?

• the producers would grow and the secondary and tertiary consumers would die

• producers would die out

• consumers would grow

decomposers are producers.

• true

• false

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

• Producers
• Carnivores
• Herbivores
• Top Predator

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

• Producers
• Herbivores
• Carnivores
• Top Predator

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

This diagram shows the amount of energy that moves from one feeding level to another in a food web.

• Energy Pyramid
• Food Web
• Ecosystem
• Food Chain

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

• 10%
• 20%
• 80%
• 90%
